Hi guys, so what i have read so far was, that msfs do not use normal maps when baking. Instead you have to create a composite material with rgb (red, green, blue) channels.
Normal works only with single texture rendered as far as i know for now.
I‘m on it to figure it out how it works. Created my first few objects for an airport and hand textured it. Today i will try and create the comp material with gimp or photoshop.
Edit: I think height maps are also not used in msfs. It‘s all about the composite.
