I recently worked with corona 1.5 daily 18th september. Some of my Trees (Forrestpack with Corona-Proxy Objects) behave funny in Cshading-RawCompontent_RawDiffuse output.
Materials are all Corona, although converted from vray.
I've no clue if that is supposed to happen - usually not - but i guess it's worth to mention, even if its still cool looking. Other outputs were done as expected.
