Might have found a bug in Studio with ' self shadowing ' when used with transparency mapped objects ( haven't done more tests to see if it affects unmapped objects ). I have a grass object that is made up from lots of single faced polygons intersecting one another. The object has double-sided turned on and the polys are uv mapped with a bitmap in the diffuse and transparency channel ( jpg in colour, tga in transparency ).

self shadowing turned on :

self shadowing turned off :

Tried turning the transparency threshold to 0 to see if that helped, but it made no difference. It was set at the default of .02 for both images.

I've uploaded a file called ' grass.zip ' to the Yahoo groups file area if you want to test it out for yourself.

This isn't really a bug and wont bother / affect a lot of people, but canging the tone mapping value affects the brightness of the material previews :p Makes sense as it's using the render engine to generate them, but I always wondered why they were changing brightness when previewing materials. Didn't think it was because I was tweaking the tone mapping value for the final renders :banghead: :)
