I have a weird problem in the material instance tab. Whenever I open a material It auto selects mesh preview with a random mesh I dont even have selected. Idk if this is a bug or just something I clicked. I have no mesh selected in the preview but this random mesh I have still autoloads everytime.
If anyone else is having the issue it seems as if I had the mesh selected as preview in the master material and for some reason it transferred so I just recompiled without it selected.
Definite a bug, I have no such behavior. Maybe reset settings or something? In a new scene does this also occur and can you reproduce it?
From what I can tell if u have a mesh as preview in ur master material and save it. The mesh will be stuck on for every material instance u use with that master material.
