• 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.

MSFS Textures bleeding through

I am currently converting my AI ships from standard FSX GMAX format passing trough wavefront obj to native MSFS with PBR in Blender - most works fine, however with many of my newer models there are issues with the areas where a polygon in GMAX was textured on both faces. If I in Blender tick doubled sided the texture bleeds through in these areas - if I do not tick double sided parts of the polygons go transparent... Any good ideas?

Double sided... the texture is bleeding through on the roof of the bridge

Single sided there are transparency issues with polygons missing

I have never had good experiences with double sided polygons in earlier versions of the sim and my rule is to mirror the opposite side, if I find it necessary to display both. GMAX to Blender seems like an adventure and obviously, you are trying to avoid recreating the entire model.

In my 3d software, I can isolate polygons, based on materials. So for me, it would be easy to duplicate the affected polygons and then reintroduce them into the model as unique, single side textured polys, after which I would check the model for visual anomalies, caused by those coplanar polygons.

I suggest you attempt this work around, if your software allows.

Thanks Rick, as I am still a beginner in Blender I don't know if and how I can do that in Blender without altering the total mapping. And, yes, the prospect of having to redo the bridge on several hundred models is not too attractive :rolleyes:

Your first image (with double-sided textures) looks like a problem of Z-fighting. Where is the American flag in your model? Is it on the ceiling of the bridge? Could you lower the flag by a millimeter in Blender and see if that fixes the bleed-through?

Well, that could probably also have solved it but would have required more work... But I realized by exporting the mdl as wavefront old obj instead of wavefront obj in MCX the problem was solved... Once again MCX saves the day :D Thanks Arno.
