Who I am and what I do:
I am fairly new to 3D modelling (still using 2.79) and at the moment I am working on an M1 Abrams low poly tank (around 4600 Tris).
What I want to do is use a copied version of the low poly tank to add extra detail to it and then bake a normal map from the high to the low poly model.
I am used to the baking procedure in cycles render with small objects (like a cube for example). That means I am familiar with the setup (image, node etc.), ray distances and so on. Let's say the basic of basics of baking a normal map in Cycles Blender.
The Problem: It starts right away. I moved the copied tank (haven't added any detail to it yet) to the same position the low-poly has and I get this as a normal map:
What do I expect:
I thought that the rays will find no difference (surface) at all because it is the same model, right? So the image should be blank. Instead I get a lot of stuff and artifacts on it.
What I've already tried:
- Playing around with Ray Distances (From 0 to 1 and between).
- Added smooth shading to high and/ or low poly model
- Removed Doubles, Rotation & Scaling
If somebody can help me?
Have a nice day.
