Working with displacement maps / heightmaps

[Sasa]

Version: 1.0.72.0

Frequency: Consistently

Severity: High

Context: Materials, projected meshes in general

Bug description:
NOT to be confused with rectangle heightmaps (DEMs)!
This seems to have been brought up in the public forums accidentally but some good points have been made there:

SDK control over Displacement Mapping in MSFS 2024

In 2024 SDK, will we be able to control the displacement mapping which is generated for all parts of the ground in our scenery? i.e Can we create an apron or polygon which states “does not generate displacement mapping here”? Or maybe control the intensity of the displacement too. Most grass runways are solid enough that light aircraft do not create massive ruts. I know its only a tech alpha, but ALL custom scenery is broken by the new displacement mapping. Grass areas which were previously 10…

Ideally it would be great a suppress terrain displacement through polygons and/or projected meshes where needed. The latter already seems to be the case as reported here:

Projected Mesh placed on anywhere else than concrete or asphalt will engrave in to the ground

Version: 1.XX.XX.X Frequency: always Severity: Low Context: any Similar MSFS 2020 issue: not an issue in 2020 Bug description: If a Projected mesh is placed anywhere else than on concrete or asphalt the projected mesh is engraved in to the grounds. In my sample i am using the ProjectedMesh i am using for the eSTOL Stol field made out of lines and a text logo which is placed on a grass, gravel or sand surface as a projected mesh. It will engrave in to the grounds so that it is not usable …

What I’m missing the most however is a way to control displacement maps through textures (in projected meshes of course, but it may make sense for other types as well?) ourself so we can add a similar level of detail to custom made bushstrips and so on… So far there’s nothing about it in the material documentation yet:

Ideally of course this approach may also give us an alternative for creating high resolution terrains based on DEMs. Alternative as in terms to the current XML based heightmaps. Just dreaming…
