Well, I still has this problem ..
When rendering trough the new cinemaxwell plugin (07-05-31)
I am not able to get the textures to mxcl...
Then I tried to extract the materials with mxed.
In a scen with 4 simple planes with diffuse material on that are named diffrently.
Only one of the 4 diffuse materials is extracted...
textures are default in real scale and inverted(!)
I am on c4d R10.1 and OSX
