- create the high poly model
- bake the textures from the high poly model (normal map,…)
- simplify the model (otherwise you will get performance problems in the UE4) + create a collision and lightmap
- import everything (textures + mesh) -> I always export and import the textures separately
- create a new material (right click onto the texture - create new material)
- assign the material to the mesh
