DataRefs Vs. Commands I: What’s The Difference

What is the difference between a dataref and a command? They serve different purposes in X-Plane, but it’s easy to get them confused, especially because the names can look so similar. If you only take one thing away from this … Continue reading

The Dangers of Wandering in the Desert

I have been trying to put documentation on the X-Plane Wiki, and use this blog for announcements and “the inside story”, rather than letting the blog turn into a poor-man’s users manual. An aircraft developer asked me via email whether … Continue reading

Broken Panels

I have found the cause of a rather serious bug in Plane-Maker: sometimes instruments disappear from the hierarchy (but are still visible in the main window). The problem is that the cut-paste facility, when used with multiple-instrument selections, was corrupting … Continue reading

Two Squashed Bugs for 930

These two issues have been discussed a lot in the forums, so I thought I’d mention them: First, I finally found and nuked that star-burst pattern in the rain.  It turns out that for some textures, compression was destroying the … Continue reading

Fixing Panel Editing in AC3D

The X-Plane export plugin for AC3D doesn’t handle panel textures very well.  The current plugin tries to identify cases where you have used your panel background as a texture – this queues it to generate ATTR_cockpit.  This scheme has a … Continue reading

The “Airplane Modeling” Datarefs

I have blogged about this before, but I will try to create one simple explanation of what’s going on with sim/cockpit2 and sim/flightmodel2 datarefs. Sandy and I (with the help of others who helped compile the list) created “new” datarefs … Continue reading

ATTR_cockpit_region – Are We Confused Yet?

The choice of panels (2-d panel vs. 3-d panel) for your cockpit and the choice of OBJ commands (ATTR_cockpit vs. ATTR_cockpit_region) both affect how your 3-d cockpit looks.  Since these two techniques can both be varied, there are a lot … Continue reading

Why Don’t Skewed Instruments Skew the Background?

With X-Plane 9.20 you can stretch the shape of generic instruments, to create instruments that appear to be in perspective.  But why does this effect apply only to the overlays and not the burned-in backgrounds?  Two reasons: Some planes are … Continue reading

When Can You Not Use DDS?

There are a few cases where you cannot use DDS files in X-Plane: Airplane 2-d panels (any layer – base, lit, -1 shadow layer, 2-d or 3-d). Airplane instrument images. Bitmap-based region specification referenced in a library.txt file. Any gray-scale/alpha-only … Continue reading
