• 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.

Frustrating PBR issue

Hello all! I've reached a frustrating impass with a model I am trying to add to my Ohio University Airport scenery add-on. I am successfully using albedo/comp/normal textures in other models on the airfield (Nice reflections where needed, nice brick textures, etc.) , but it seems this one just always shows up in MSFS as matte, while it looks really nice in blender:

vs MSFS:

I cranked up the shininess in the comp file purposely to try to affect it, so the aircraft skin is a little TOO shiny now. In the blender image, you can see the important parts of my shader including the gltf settings which I made sure were the right ones (The wrong ones produce a pink texture in MSFS)

Things I've tried:
1) Made sure all face normals in blender are facing out
2) Inverted the Y on the normals texture
3) Inverted the colors in the Red channel of the comp texture in case I was using the wrong logic (White = light hits it, Black = shadowed)
4) Inverted both the Roughness and Metallic (G and B) channels in the comp texture, though I understand their logic
5) Cranked up the normal multiplier in the MSFS portion of the blender material but this makes it look horrible, obviously

Here is an example of the Albedo/normals/R (ao)/G (Roughness)/B (Metallic) from my texture files:

And here are my Material setting for MSFS:

Does anyone see anything glaringly wrong here, or have any idea what could be causing this?

Thanks!

ok, so I rebuilt the material from scratch and it works now! I guess something was just hosed with that material

FYI, the material channel slots of a PBR texture are controlled in shades of black and white and you can confirm this fact by examining any default COMP texture. Your image shows color in each channel, which will be desaturated into it's relative grayscale when rendering. This, of course, prevents the intended absolutes, as 0,255,0 is absolute green, but it desaturates to 150,150,150, a somewhat darkish gray. 255,255,255 in the green channel, is absolute roughness, while 255,255,255 in the blue channel, is absolute "metallicness."
