i have slabs on top of stairs and you can see through the slabs? this happened to other parts of my model as well, this is just one example. This is a model i made in blender and imported into unreal. I’m pretty new to unreal, if you need more information pls ask
Bear in mind, you have to import the textures and make the materials yourself after importing meshes from Blender. The process is not automatic.
If it’s not that, then maybe upload the FBX of the stair model here?..
