I am currently making a decently low poly model to fit a specific style. I do not want to make a higher poly version purely for baking.
The procedural bump is just a noise texture, with vertex colors to control the intensity, to use as normal map clothing wrinkles. Procedural mat shown below.
What I expected when baking these to a texture was for it to bake just the bump from the noise texture itself. However, what baked instead was the noise texture, as well as sharp blocks of normal data that seemed to follow the angles of the low poly parts of the geometry.
When applied to the model, these normals don't look correct whatsoever, and the blocky parts are extremely visible despite not being there in the procedural version. How can I get it to bake PURELY the noise texture, and ignore the actual geometry? Do I have to find some kind of workaround or is there an easy way to fix this?
