• 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.

Mesh / Material Issues help [3ds Max 2022]

Hi!

So I'm getting back into MSFS development after a year hiatus and I am working on getting our model into MSFS ready for testing and development, however there are some normal issues that I have no idea how to fix. When the material is set to "Standard (Legacy)" they appear just fine, however whenever I set the material to "FlightSimulator" I see these weird normal issues, however they only appear in these areas. Could anybody shed some light as to what is going on here?

Thanks!

When I am in clay mode however to view the mesh, the issue does not show up, so I'm assuming it's some sort of material issue...Here it is in clay view:

Hmmm alright...but I'm still not sure that is the issue though as it seems to only be affecting the albedo channel and nothing else...look at these screenshots below...with the Roughness & Metallic channels + Normal map, it looks normal but the albedo still looks messed up...

How would you see there is no distortion in roughness, or metallic? Albedo is the only "visible" channel, are you saying that you see some sort of repeating distortion pattern that is revealed in the relative glossiness, or relative shininess, of the affected polygons? In a still image?

Anyway the problem is clearly in the polygons, too many sides, or reversed, but this is payware right?

What I'm saying is that the issue is only visible in the albedo channel, but I will try some mesh cleanup today when I get some time to see if that fixes anything...and yes this is going to be payware :)

With torn vertexes, this happens either along the mapping cut line. Also try to check the polygon smoothing parameters, maybe there is a connection of edges or polygons in different smoothing stacks somewhere. Sometimes previously baked anti-aliasing maps are stored in the mesh and are not changed in the parameters of the mesh itself. It is possible to perform MeshSmooth on a part in Editable Poly, set Iterations to 0 and save, which fixes the error.

I have had this problem in the past myself.
I would recommend welding the problem vertices were possible.
This is never a sure thing but sometimes helps.
Of course double checking normals in the problem areas.
And if you are using smoothing groups double check values in the problem areas vs the adjacent areas that are working.

BTW I am having a terrible time making sense of the FlightSim material type and its usage.
Also the Pearl option.
Can your recommend any sources.
The SDK docs are almost useless.
Thanks.
