New versions 7.10/7.11 have errors with model normal maps

This is the model import in the new version (7.11 in PG)

This is the model import in the new version (7.5 in PG)

I updated from 6.x to 7.5 without any issues. However, after updating to 7.10.5 today, I noticed that the model normal maps are inverted. Unfortunately, I can’t provide a PG (as shown in the image, the file is too large), but I’m confident this issue can be easily reproduced.

This doc page can help you store your asset where it can be linked from a PG:

It will be easier for us to find the problem if you are able to provide a PG.

In that json string is there something with “sideOrientation”?

Nice intuition @Joe_Kerr
I think I will have to keep the overrideMaterialSideOrientation and flag it as deprecated
