View Full Version : batch render produces brack images with mental ray

04 April 2007, 03:55 PM
Hi, Im rendering images fine in the render window.

When I batch render the same scene with mental ray, all I get back are black images.

Does anyone know what could be causing this?

Well Ive gott a good one for you , my reflection pass has a animated IBL node just in Y , it renders fine in viewport and the reflection moves accross the surface fine , but if you batch render it it wont render correctly ie the reflection will not move accross the surface......

Project set? Files where it can get to them? Can be a lot of things honestly.

For the IBL, if it is animated you need to kill the "Optimize Animation Detection" in the Translation>Performance section of the render globals. (I think that's the one at least.)
