i see a very particular problem when i load a texture and try to select the alpha channel.
here the image that show what i do.
_<_img border="0" src= "http://www.tarabella.it/c4d/vrayforc4d/alphaproblem.jpg"_>_
after that.. the rendering in the material always return RAY_USERBREAK and the MATPREVIEW_GENERATE_IMAGE is called until all crash... but if i start render on picture viewer... the render of alpha is good.. and the material preview is updated in a correct way.
Same problem if i try to render in a viewport, but if i start render in picture viewer and then start rendering in viewport.. all go fine.
seem that there are different levels of rendering.
Another strange things is that if i try to render with scene motion blur my scene. all ok except the texture or shaders are not traced.
Thanks for the support
