They were separate objects, but when merging them, I still had the same problem. (I merged them to make it easier to animate the chest to open in my game) As for the material bit, I assigned UVs to three different textures in blender. I will give you the .blend and pictures now.
As far as materials go with blender, I don’t have any experience, but in the past, I could just UV wrap different textures, and exporting it would be just fine. But sometimes this just doesn’t work, and I don’t know why.
This model uses three textures, one that is a solid white image, pink boards, and then the texture for the keyhole. However, when I import this model as an FBX into Unreal, I only have one material slot instead of the three I need! What is going wrong? Is there something I’m overlooking in Blender?
By the way, I’m aware that a workaround would be to uncheck the “combine meshes” option when importing, but this doesn’t actually solve the problem as to why there’s only one material slot in the first place. It’s really annoying to have to reassemble the model in UE4!
