Changing Prefab Meshes
I started creating a game using cube place holders. I've made some objects within blender and thought it would be a smooth process of just changing meshes and inserting the shaders. I imported the object (.blend) just fine and it looked correct, but when I tried to swap the mesh with the cube place holder it removed the inner part of my object.
The problem is the game is a puzzle game and I already created 25 levels using the placeholders so I don't want to have to replace all of them manually, which comes with an additional question of how do I properly set of the materials in Unity? I attached 2 colors to the blender file, but since I'm adding mesh to an already existing prefab how do I set up the materials to look like the blender object.
Thank you so much in advance! (First image: What it should look like, Second Image: Missing inner cube and has the prefab red material)
