Seem to be having this issue but in a very weird way. I have a datatable thats loading in different types of meshes with different materials etc but now a lot of them dont spawn the material properly.
I imported two meshes (no materials) and this popped up, clicked done and now whenever I play, the materials of other meshes get messed up, even though it has nothing to do with the meshes I imported.
the material above is being put on it when it should be this:
In the mesh editor, it looks completely fine, nothing wrong with the materials, only when play is pressed does it not spawn the materials correctly.
When I look at reference viewer of that material thats on it, the MI_ProcGrid (which is an engine landscape material it seems), it links into the base mesh that is used as a placeholder mesh if one cant be found in the datatable of meshes. It also links into all the maps.
Its definitely an engine problem as I have swapped branches in my source control and that doesnt change anything, it happens on every branch, even really old ones.
I have tried redownloading my repo, and updated the engine (im using 5.0.3) and verified the engine files. Nothing has helped. Next thing to try is to uninstall and reinstall the engine but I really dont want to as that will take ages and I have other projects that im working on.
Anyone know why its replacing the materials with this ProcGrid one? Im baffled at this point ;(
