X-Plane 12 has a new set of textures and other art assets. The main idea behind this pack is the general improvement of airports – particularly the depiction of the ground surface. All features in this pack comprise POL, LIN, or simple OBJ assets, and all of them are “ground” oriented. Here is an example of what can be achieved:

The assets in this pack are divided into four categories:

lib/airport/ground/pavement

lib/airport/ground/pavement_FX

lib/airport/ground/terrain

lib/airport/ground/terrain_FX

We can understand these four categories as different groups of layers in the following order:

4 – pavement FX effects placed on, or snapped to paved surfaces (cracks, dirt, grunge, drains, etc.)

3 – pavement main hard surfaces (asphalt, concrete)

2 – terrain FX effects placed on, or snapped to natural surfaces (paths, grass patches, lawn tracks, etc.)

1 – terrain natural terrain (grass, desert, etc.)

A higher value means a higher priority of visibility. In other words, terrain FX won’t be visible through the pavement but the pavement FX over the grass will be shown. That means you can paint a dirt path across the border of asphalt, but you shouldn’t paint asphalt cracks across the border of grass.

1 – Terrain

We have brand new textures and shaders for all basic airport terrains. The grass is completely new, the desert is new, and so on.

In addition, we have unique grass textures with lawn-mower tracks. This is a typical detail that can make the terrain look more realistic. These textures are directional so for better plausibility, it is very important to set the proper direction in WED polygons.

Ter 02

Next, we have textures for sand and soil. It can be useful for various patches in the grass.

Ter 03

2 – Terrain_FX

This is a group of effects that can be placed on top of natural terrain.

lawn_tracks

The lawn-mower tracks effect comes in different forms. POL (polygon) files have a similar visual effect to those above. This time, however, they are transparent and contain only the lawnmower tracks themselves. It can be placed on top of any type of underlying terrain (which can be handy for locations where nice green grass is not desired).

Terfx 02

LIN (line or stripe) files are useful as a natural border between grass with a lawn-mower effect and surrounding areas. Typically these can form the natural shape of grass islands in between taxiways. We have various strips with corresponding colors of grass.

Terfx 01

Typical use:

Terfx 03

OBJ (object) files are mostly spots with a couple of tracks in circular form. These can be placed typically in corners, or under various things in the middle of the grass (like taxi signs).

Terfx 04

patches

Patches are available as single OBJ (various sizes and shapes) and as LIN (various widths). We also have all corresponding colors for basic terrain polygons – grass, dark grass, dry grass, light and dark sand, and soil. They’re useful for modeling various imperfections in basic terrain, spots, broken lawns, and so on. Also, these can be used along the edge of a taxiway, as an extension of the natural edges (see below).

Terfx 06

paths

Path LIN are available in various widths and materials (concrete, sand, and soil).

Terfx 07

taxi_sign_base

These are paved bases for taxiway signs. Single OBJ are available in various sizes, and two colors (light and dark). If you can’t find the desired size for a certain situation, you can also use the LIN variant. These OBJ have an exception to the layer system described above. They render above the pavement so you can use them also on top of taxiways.

3 – Pavement

In X-Plane 12 we also have a brand new shader designed particularly for hard airport surfaces. Generally speaking, it can make better-looking asphalt and concrete, with less obvious texture repetitions over large areas (almost invisible repetitions).

Pave 00

asphalt_

Asphalt surfaces are available in five basic colors (light to dark).

Pave 01

Each color variant is available with four different effects:

1 – plain: this variant is omnidirectional. It is useful for specific situations (typically taxiway shoulders) in conjunction with various effects (see below).

2 – strips: this is probably the most common variant with typically visible strips.

3 – worn: same as (2), but a bit worn. Gaps between strips are sometimes cracked or patched.

4 – patched: highly worn, irregular, and more visible cracks.

Pave 02

concrete_

Concrete doesn’t have a unified system like asphalt. We have three main colors (gray, light gray, and dark gray) but with slightly different effects for each of them. In addition, we also have the fourth color group which is tinted (red or yellowish). Here are some samples of the variants:

Pave 03

4 – Pavement_FX

This is a group of effects that can be placed on top of hard surfaces.

edges

Probably the most important asset. Edges are dividers of pavement and natural surrounding terrain. They are available in two colors (light and dark) and have three variants:

1 – soft: basic edge with a slight plastic effect. Suitable for most common situations, particularly for grass.

2 – elevated: pavement surface looks slightly elevated, and the edge is a little worn.

3 – cracked: a lot more cracked and worn.

Pavefx 01

gaps

These are dividers of adjacent asphalt or concrete surfaces. A wide patch line can be used for manually painted large-scale cracks, however we recommend you do not repeat this small texture to cover large areas.

Pavefx 02

taxiway

Here we have four different types of taxiway structures. Imagine transparent strips, with the very subtle effect of dirt on asphalt. These were designed to be used in conjunction with the plain variant of asphalt. These are useful for curved segments of taxiways and particularly shoulders, and are available in different widths, which should roughly match the usual sizes of shoulders.

Pavefx 03

taxiway_cracks

Another kind of effect that is useful, especially for shoulders. Also available in different widths.

Pavefx 04

taxiway_dirt

In this group, you can find subtle dirt effects. Some are designed for placement along the centerline, others are for the edge of the taxiway.

Pavefx 05

drains

Various drains and manhole cover lids.

Pavefx 06

General hint: most LIN effects have end caps. That means the line needs some minimum length. Any time you see an artifact (black rectangles), it is probably due to insufficient length of the line.
