• 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.

Hey guys, trying to figure out how to do PBR textures and really struggling to make it work right. Starting off small with this simple box used to store fire extinguishers etc, been trying for a while now, one thing I don't know how to fix is the fact any faces of the object that are not in direct sunlight are black, not darker, just black for some reason, and the metal bits are also dark, anyone know how to fix this?

Also if anyone knows of a really step by step guide for TOTAL newbies that would be great, I can do models in blender but the textures side of things is kicking my butt and I haven't seen anything that doesn't go too fast and misses steps explaining everything needed to be done.

Thanks.
 
Can you please tell us what a "comp map" is? MCX offers 9 texture slots; albedo, bump, diffuse, emissive, environment, Fresnel, metallic, normal and specular. I do not believe there is an ambient occlusion map, I believe AO rendering is calculated from geometry, but this is not a conviction.

Based on information in this article, it seems possible you refer to the albedo map, is this correct?

What are the different texture maps for?

In this article you'll learn what all the various texture maps that make up a Poliigon Material are for.

However, MSFS does not support a "color map," so the implication would be that albedo maps must have no shadows at all, in order to render properly.
 
MSFS PBR textures use an albedo map, a 'comp' map and a normal map. The comp map has is made up of:
R channel: ambient occlusion
G channel: roughness map
B channel: metal map

I've never used MCX for MSFS, as I export directly from 3DS Max, and make my own comp using Materialize, but from a quick look, it seems that MCX uses the 'metal' material slot for the comp texture. Or to put it another way, it calls the comp material 'metal'. I'm not sure how MCX handles this, but I would guess that if you've ended up with a comp texture by any means, your R channel (AO) may be black, rather than mainly white. Some more info on the steps you've taken would certainly help.
