>would it be possible to generate a reflection mask with Smart multipass?
you mean a matte of the reflective areas? yes.
you just drop the multipass buffer into the reflection channel, hit "add buffer" and your done. from there , anything that uses that material will write to the buffer you have created.
No, i mean a mask off the reflection itself. Right now i have to do a second render without lights where the reflected material has a pure white in luminance...
Anyway i just bought your plugin, this will save me a lot of multiple rendertime hopefully.
