X-Plane 11.20r1 Available

Before Ben left on his family trip (and he was very adamant that it was not a “vacation” because the kids were going along) we got an X-Plane 11.20r1 build ready for possible release this week. Tyler and I must feel lucky because we’ve gone ahead and pulled the trigger to make this build public now.

This means that we need you to test your add ons now–seriously we mean it–speak now or forever hold your peace. All our features and changes that are going in 11.20 are in*, and the only changes we will put in from here on out are any regression bugs you bring to our attention. Read More

X-Plane 11.20b5 Is Out

X-Plane 11.20b5 came out this week – notes here. Beta 5 fixed the rest of our open rendering engine/material bugs, including artifacts on orthophotos. If you are a scenery or aircraft developer, please check your aircraft or scenery against 11.20 beta 5 and make sure there are no rendering changes compared to 11.10. If it looks different than 11.10 in a bad way, we don’t know about it and it’s not going to be fixed if you don’t say something.

Over the last year we’ve been working quite a bit internally to automate testing. We still do a lot of hand-testing (that is, Jennifer flies the sim and then tells us we’re bozos) but we also have extensive infrastructure to script the sim. So we’re looking to automate the process of checking third party scenery for rendering artifacts, so we can catch more rendering bugs more often.

I’ll post once 11.20 is final about how to get your custom scenery into our test. My hope is that with automation, we can catch bugs faster and you (the third party author) can have your add-on tested without having to do the work yourself.

I’m OOTO next week but if things go well, we’ll have a release candidate when I get back.

More X-Plane, More WED, More Docs

After much bug fixing, X-Plane 11.20 beta 4 is out – here are the fixes. This beta fixes Linux performance, a few material rendering bugs for custom aircraft, and a bunch of X-Plane SDK bugs for VR.

We have a new WED 1.7.0 release candidate – hopefully the third time’s a charm!

And…we have docs on the vrconfig.txt file format. The VR config file is used to add VR-specific data to an aircraft, including:

  • Hot spots for seats (E.g. where does the pilot sit).
  • Extra data for manipulators.
  • Parameters for the yoke in VR.

Please do not ship your add-ons based on 11.20 VR tech – wait for us to go final. All file formats are subject to change during beta!

We are reaching the end of beta, for both WED and X-Plane. We’ll see, based on incoming bugs, whether we need a beta 5 before RC; hopefully WED 1.7.0r3 is a keeper.

Beta 4 and VR Docs Are Coming

We’ve been working on 11.20 beta 4 for a while now – the goal for beta 4 is to fix all of the SDK/authoring bugs and have docs for the new VR file formats. We’re making good progress; beta 4 should be this week, barring an unforeseen bugtastrophy. (Linux users: perf should be fixed with beta 4.)

We received a number of bug reports that beta 3 was showing large numbers of _vrconfig errors with third party aircraft. So this seems like a good time to re-iterate our policy on file format stability and betas.

  1. Don’t ever ship an add-on that uses an undocumented file format. You can’t guess what the fine print is from example aircraft.
  2. File formats are subject to change during beta, and are not stable until we go final. Don’t ship your add-ons against beta file formats.

In our case, the _vrconfig.txt file format changed in beta 3 and will change again in beta 4; as Chris wrote docs, he found issues that he is fixing.

Our priority during beta is not stability of your add-on, it is getting the file format right, so we’re not stuck with a buggy file format for the rest of time.

Once we go final, we’ll put compatibility code in to support the final version shipped in X-Plane when needed.

Similar logic applies to the SDK – it’s fantastic that people are using the latest SDK to test their plugins in VR, but don’t hit the “ship it” button until we’re final – it is always possible that the SDK will change in a way that breaks compatibility during the beta.

X-Plane 11.20 Beta 3 Is Out

Release notes detail the bug fixes here. We have another set of bug fixes that will go into beta 4 next week.

We’ve received a number of bug reports from plugin developers trying to use the new plugin APIs. We’ll have another beta next week to address the rest of the open issues, including the ability to (finally) use widget-based UI in VR.

Beta 3 fixes the MFD brightness going crazy in the G1000 C172, and fixes shadow casting on transparent-alpha-textured objects, but we still have an open bug with panel brightness in a Carenado aircraft that looks like a low level rendering bug. 11.20 has a lot of change to the rendering engine to support VR, performance and our migration to Vulkan and Metal, so authors: please be on the lookout for changes to how your models render compared to X-Plane 11.11.

If beta 3 isn’t found to be a smoldering wreckage of poorly thought out C++ over the next day, we’ll post a Steam version of the beta.

X-Plane 11.20 Beta 2 Is Out

It’s like beta 1, but without the missing art asset. 🙂

We’re working on beta 3 now, which will have some fixes for rendering bugs. A few notes:

  • This is not going to be a typical eight-week beta. Please go check your add-ons this week.
  • The biggest area of code change for VR that affected other parts of X-Plane was the rendering engine. I’ve fixed 3 rendering bugs where I broke something while restructuring the renderer for VR, and none were surprising. Please check your aircraft or scenery pack for visual defects and let us know!

Steam users: we should have beta 2 up shortly.

WED 1.7r1

Release candidate builds for WED 1.7 are now available for testing. A big thanks to Michael for leading a lot of this development. He kept all this moving along at a much faster rate than if we’d been left to our own devices! Here is his summary of the changes you’ll find in this version:

Selection of items

When selecting any item in the map pane, WED now prioritizes the items by a what appears to be on top when viewing the scenery in X-plane. So if you click on any .OBJ in the middle of a taxiway – it always selects the .OBJ, line marking or ground painted taxi sign rather than the underlying taxiway. Similarly, it selects the facade or forest rather than anything that is flat and draped on the ground.

Technically, this means object type and LAYER_GROUP rather than WED hierachy based prioritization.

Exclusion zones and airport boundaries are now kindof “hollow” items, they can no more be selected by clicking inside of them, but only by their frame/outline or perimeter. That should greatly help with not having to lock or otherwise get those large area items out of the way.

All items can now be single-click selected, even if they are located within the area of an already select item. This eliminates the need to de-select (CTRL-D) e.g. a taxiway every time the last attempt to click select a .OBJ turned out to be just a bit to far away. And therefore accidentially selected the whole taxiway underneath it instead.

Drag-moves are now subject to some “stickyness” , i.e. the move/copy only starts after the drag exceeds a few pixels. This helps avoiding accidential very short distance drag-moves. Once the item has “broken free”, the item can be moved back to within a single pixel of the initial location, so small moves can still be achieved.

Several bugs that prevented adding bezier handles to nodes under some conditions or selecting very closely spaced items are fixed as well. All operations now require a click no closer than 4 pixels from the “correct” location. Any very closely located items having the same piority (like two nodes of the same polygon) are now selected using a “whatever is closest” strategy, rather than having overlapping bounding boxes prevent access to all but one of them.

Validation warnings and results browser

Some validation issues can now be a warning only, rather than a hard error. This allows WED to try more validation of frequently found problems, even at the risk of creating a few false alarms in rare cases. If such a warning is ignored for gateway submissions, the gateway moderator will determine on a case-by-case base if the issue can in fact be waived or still reject the scenery submission.

After validation, a full list of ALL validation issues will pop up, allowing to browse and zoom to / highlight all issues to help planning out the work required to pass validation. This also allows to select multiple validation errors to e.g. select ALL duplicate vertices in ALL polygons – allowing to fix all with a single editing operation.

New validations

Validation now catches all types of self-intersecting polygons. Previously there were certain cases of bezier-curves that caused taxiways/polygons to stop showing up at certain zoom levels or not at all in X-plane, despite they looked fine in WED or vice versa.

The coordinates and names of runways need to be exactly in sync with the CIFP data used by X-plane for FMC SID/STAR and GPS approaches. For this reason, gateway airports are occasionally edited by a script by “WEDbot” to achieve this, but any user re-submission that touches the airport may break this effort. WED now validates the runways against CIFP data oit obtains direct from the gateway server and requires the runway threshold to be within 10m of the exact location. Note this is the thereshold – the wide white bar only.

There is a separate warning only if the displaced part of the runway (the optional part from the end of the runway to the threshold – with the centerline arrows pointing towards the displaced threshold) mismatches official documentation. Some of the CIFP data mis-states that displaced distance, so it is a warning only. Please thoroughly verify such warnings against current orthoimagery and draw as per current real world markings.

A *lot* of ATC flows on the scenery gateway are non-functional because of misunderstandings how flows work. The most common mistake is to define one flow per runway and then expect that X-plane somehow finds all flows that fit the current weather pattern and uses them all togther. But that’s not how flows work. Validations will now try to find such duplicate condition flows (that are effectively never ever used) and will warn about it.

The airport naming is covered by several new errors (like ALL CAPTIALS – THATS SHOUTING IN THE INTERNET AGE !) and warnings if undesired elements are included in the names.

Smart runway rename

When a runway is re-named due to magnetic variation changes, not only the runway name, but also all ATC taxiroutes, flows and taxisigns need to be fixed up to reflect the changed designation. WED now will detect such edits of a runway “name” property, find all these references, update them and let you know. This greatly helps when the runway validation tells you it’s missing some runway at that airport – which usually means some existing runway was recently renamed due to magnetic variation changes.

More library item previews

Type 1 facades are now displayed in the library preview panel. Please be patient – the more complex “type 2” facades as used in all airport terminals and the new terminal kit are not showing, yet.

Many library items come with multiple variants that X-plane will select at random from when placed in the scenery. For such items, a button will show up to view each variant. But keep in mind – there is no way to tell X-plane to always use a specific one. Its just a true “FYI”, only  …

All forest/facade/object previews will show some textual information about their size and features available.

The World Map in the background now has 9x the resolution and shows true X-plane ground texture colors.

ATC taxi route names are displayed in the ATC TAxi & Flow view – please verify them for consistency, as the X-plane ATC uses and even speaks these names when providing taxi instructions.

Don’t import from the apt.dat for gateway airports

The apt.dat and .dsf formats are lossy, i.e. they contain less information and use less precision than a direct import of the airport from the scenery gateway. WED will now warn anytime it detects such an import for an gateway type airport.

Upon im/exporting to/from the gateway WED will now also show warnings if the gateway is currently not accepting new submissions for that particular airport.

Facade editing

Facades without roof’s or filled areas, like fences and skylights in the XP11.10 terminal-kit are now allowed to have 2 nodes only – previously facades of any type had to have 3 nodes minimum.

Two bugs were fixed, too – these prevented selecting certain wall types in the terminal-kit facades and displayed some facades as being “closed rings”, rather than line-type items in the map window.

Orthophoto import

Georeferenced image “geotiff” import used to require mercator projected, WGS84 referenced coordinates. On Linux and OSX it will now understand pretty much all coordinate systems defined in the EPSG standards – although WGS 84 lat/lon coordinates are still the preferred encoding.

Display speed and memory use

When zooming in at airports with very large, single piece taxiways, the WED display speed used to slow down significantly.

The 64-bit versions of WED (OSX & Linux. Windows is still 32 bits, only) used a lot of RAM with large sceneries, e.g. im/exporting the *whole* global airport scenery (thats what WED is used for at LR, all 28,000 airports in one scenery !) maxed out a 16GB RAM machine. Now its down to near half that and everybody else gets a small speed boost, too.

Preferences menu

Some user adjustable settings (like meter vs feet) are now moved to the File->Preferences (OSX: WED->Preferences) menu, stored in WED’s global preferences and no more loaded/stored with each individual scenery file.

Now Serving 11.20b1

X-Plane 11.20b1 is the first beta that includes non-VR improvements. Full release notes are here, but a non-comprehensive short list of the most exciting additions is:

Formation flying: this beta includes Jörg’s new code to improve network sync, both for external visuals and multiplayer/formation-flying. X-Plane now calculates the total latency between machines and adjusts network aircraft to compensate, with error correction. This means you see your friend flying where he is, not where he was when X-Plane sent an aircraft position update over the wire 100 ms ago.

Night lighting: X-Plane’s night lights come from the autogen, but for performance and memory reasons, X-Plane doesn’t build autogen far from the aircraft. Petr has added night lighting textures for the far view to fill in the night sky. Here’s a comparison at KSEA (looking toward KBFI) at about 10k feet.

New Sydney landmarks:

Steam users: the beta will be up on Steam over the weekend if we don’t find any major problems.

This is going to be a relatively short beta – most of the technically risky stuff went into the VR previews. We still have a plugin bug with fuel flow to fix, and Linux performance problems to investigate. Third party authors: please try your add-ons on an 11.20 beta soon.

X-Plane 11.20 VR6: Can We Break the Curse

X-Plane 11.20 VR preview 6 is out, and if preview’s 2 and 4 are any predictor, it’s going to be a dreadful disaster, as all of the even number previews have been so far.

But maybe not! Maybe we can break the curse – after all, Star Trek did it with Nemesis. Anyway, VR6 is available for public beta. Steam users – we’ll post it on Steam tomorrow if we haven’t found a major problem, otherwise we’ll go right to 7.

Highlights:

  • Asynchronous Space Warp (ASW) works for the Oculus Rift.
  • No more white instruments.
  • No more crashes loading some third party aircraft.
  • The xPad won’t follow you around as you teleport around the tarmac.

Depending on how things go, this might be the last VR preview! ASW and xPad teleportation were the last two big VR specific issues; if things go well, we’ll produce a general 11.20 beta for everyone with the other features mixed in. I’ll post about that next week if VR6 doesn’t have to be recalled for insubordination.

We Are Now Just Like Star Trek

Fellow nerds^H^H^H^Htrekkies^H^H^H^H^Hnerds are aware of the even-odd phenomenon – for nine films, every other Star Trek movie was pretty bad, then the next one would be okay. VR previews are now like that, with VR2 and VR4 being fatally broken. We’re planning to just skip 6 entirely.

Anyway, I broke VR4 – my code to put a loading screen in the Oculus Rift had a side effect of killing the render resolution on the HTC Vive and WMR-based headsets. Since I only have the Rift (Chris has one of everything) I never saw the bug; since I thought my change wouldn’t affect anything outside the Rift, Chris didn’t re-try the Vive.

So, VR5 is now up – this should restore the Vive/WMR headsets to the performance of VR3.

We can confirm that ASW is not working in VR4 or VR5 – we’re looking at this now, but for VR4 and VR5 you’ll see ATW but not ASW, regardless of Oculus debug settings.

(Edit: the first version of this post confirmed no ASW in VR5. ASW is off in both VR4 and VR5 because the native rift SDK is not permitting ASW for X-Plane. A number of commenters were concerned that they would lose ASW by going from VR4 to VR5. You will not! ASW is already off in VR4; if you like VR4’s performance, you clearly don’t miss ASW.)

(Edit 2: We have a very promising lead on the ASW issue for Oculus. We have it working again here but I want to do more testing before I declare victory. We do not need any more information. Nothing you can do on your end will fix this. If you think you’re fixing it by “jiggling the handle” you’re probably just falling into placebo effect. If everything goes well we will have an update to fix this over the next day or so).
