• 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 Wrong reflection with PBR material

Hello!

I've got some really weird reflection on my metal parts. I feel I'm on the cusp of finding out what I'm doing wrong, but it would really help me out if someone could point me in the right direction. Here is the problem, it's hard to explain except by "when a metallic material is applied to a sphere, the reflected horizon make a ying yang symbol".

The material on the sphere is the same as the one on the nearest building's roof. This is why it appears green, but being corrugated metal plate, it should reflect the sky.

These are the textures before their export in *.DDS by the Scenery Editor.

It seems to be coming from the normalmap : when I try a material without, the reflection is fine.

Thanks for your help,

Bruno.
 
I am using the same texture in one of my airfields, but do not experience this problem.
Could it be the UV mapping is rotated 180 degrees? It looks in thee video as if the roof plates are pointing in the wrong direction. You use a checker texture with numbers on it for the albedo, to see if it needs to be rotated.

Ah yes, good point. I'll check.

=> I checked, and sadly that's not it.

Maybe there's something wrong with the material altogether, I didn't feel I had the problem before, but again it's the first real metallic texture I got on my scenery.
 
If you are using textures that are pre-made, then I would suggest you double check on how the normal maps were made, either OpenGL or DirectX. If they were made by means of OpenGL then you will need to flip the Y-axis, the Green Channel.
