Set Material node not setting materials

I’m using a Set Material node in one of my blueprints and it fails to apply material I want.

As a result I end up with no material at all on the selected part of mesh. (default grey checker thingy appears instead)

edit:

Apparently it works with some materials and doesn’t work with others. No idea what it depends on.

example:

M_Metal_Steel works fine

M_Brick_Cut_Stone doesn’t get applied

Can you check if all materials compile successful?

They do. The ones i mentioned are from starter content. The one I want is simple material with base color + emissive color pulsing. Also compiles with no problems.

What material index you have on that part of mesh and what index you set in SetMaterial function?

I just discovered it’s not even blueprint problem anymore. The material doesn’t get applied manually on that mesh. Sorry - didn’t check this before posting.

The blueprint was set up properly. It’s just the mesh&materials not being compatible or whatever.
