Scaling a quad randomly breaks lighting and normal mapping

I made a 1x1 quad with a surface appearance on it with just some normals.

When I scale this quad, the lighting completely flips randomly.

I’ve included a test place.

Expected behavior

The quad should look the same no matter what the scale is.

Note: This is not the new edit mesh stuff, this is just a regular ol’ quad meshpart.

Thanks for the report! Just to confirm, we have a ticket for this in our internal database.

I’m no longer seeing this issue occur when scaling a quad but simply rotating it seems to affect lighting in the same way :upside_down_face:

The issue around scaling breaking normal maps should have been resolved. We are tracking the issue with rotations affecting lighting on normal mapped surfaces separately and will have a fix for this coming soon.
