I would like to see how my x-trees look in blender cycles renderer with the faked cylinder effect applied by racer's standard_xtree shader . Ref. http://www.racer.nl/tutorial/xtrees.htm Supposedly one can script "ad hoc" OSL shaders into the blender shader nodes screen. I think racer's .cg language is the same as Nvidia Cg. Any porting references, cookbooks, or pointers you've found valuable? Thanks.
