I have been doing some experiments with texturing (when my surroundings have allowed it), and I have found that Sunflow can do a lot with texturing that I was not aware of.
Among the features listed for Sunflow we can find Bump/normal mapping via surface modifiers. I have studied the Wavefront mtl-bible and tried my best to get this to work, but I must admit that my skills are not nearly what I imagined. So I give up and ask for help:
Does anyone know how to implement bump/normal-mapping for Sunflow?
It really makes a difference.



The obj file and the bump map can be downloaded here
