• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

MSFS20 Why do some of some materials look vastly different in Blender and in FS? (problem)

Issue: Certain materials are displayed in quite different fashions between Blender and FS20.

Breakthough is as follows. I attempted to create a wooden plank texture. First I used Node Wrangler to create a material from a texture package. It had the following contents:
  • AmbientOcclusion.jpg
  • Color.jpg
  • Displacement.jpg
  • NormalDX.jpg
  • NormalGL.jpg
  • Roughness.jpg
The 1st try looked like this:

If it matters, there's a plane mesh on top of everything. It includes a dirt texture, which doesn't look right here. It is set as "Decal" material in Blender.

Therefore I checked the logs and saw warnings:
vgy.me

I suppose "AmbientOcclusion.jpg" is the mentioned occlusionTexture. metallicRoughnessTexture doesn't exists?

Based on that I deleted ambient occlusion nodes from the materials (planks and supports) and it now looks like this:

The aforementioned procedure didn't do squat, as the same errors keep showing up.

Therefore, in sim, the plank material seems broken. It is repetetive, streched and nothing like in Blender.

(I created the first 3 planks manually and then used the Array modifier to create some variation.)

Weirdly, the different wood material beneath the planks looks passable.

What's the problem with my workflow?

You're not using MSFS materials. You need to take the separate Ambient Occlusion, Roughness and Metallic textures and combine them into a single metallicRoughnessTexture. MSFS won't do it for you nor will the exporter. If you get 3D texture packs from the internet they will have the textures separated but this won't work in MSFS.

You then use the MSFS plugin to add an MSFS material and fill the slots with Albedo, the metallic roughness occlusion texture you made and the normal map.
