I am using Unity3D to make a platform game and want to create my platform blocks using Blender. I have created several platforms meshes of different types for experimentation within Blender to find the best approach but I keep running into the same problems.
A little context, all platforms started life as a cube that is then extruded and manipulated as needed. I would also like to have the edges of my platforms rounded with a bevel and I have smoothed normals to make it look rounder.
However, I am having a nightmare with UV unwrapping. How can I a) extrude platforms where each face is mapped to a texture atlas? b) have rounded edges without messing up the UV coordinates?
Any advice would be very kind
