Hello, I’m currently converting a project from 4.19.2 to 4.20.1 and it would seem that one of my materials is no longer functioning properly.
The mipmaps generated seem to be behaving differently.
Here is my scene in 4.19.2: pre conversion. (Scene setup is slightly different but the ground mat is the same)

Here is my scene in 4.20.1 post conversion.

It would seem that mipmaps are kicking in based on the angle you are viewing the surface at as revealed in this video here:

And for some reason there are no options to disable this, and it doesn’t seem like offsetting the LOD bias by a few negative values will offset the mipmap generation either. Not quite sure how to resolve this and while I could probably procedurally generate a 128x128 alpha texture it would be nice to know why it’s behaving this way when historically it hasn’t. Could it be something to do with the new proxylod stuff?
My mipmaps, if you’re curious:
