I create a glass material and it will just compile on basic shapes like an cube. If I put it on a more complex mesh it will stay blank. Same issue with a grass texture, wont compile. Both work with the same workflow and material in ue4, how can I fix it?
Check if you have Nanite enabled on the meshes that are giving you trouble. I donโt believe transparency/alpha enabled textures work on meshes that have Nanite enabled.
