So I have this project in Maya 2013, I am trying to render a walkthrough through an interior (there are several lights in different places) with render batch. Problem is when I render a still frame it looks perfect, when I do it with batch render the lights are not activated or something. It is not a camera problem because same thing happens with another camera and with perspective. It has something to do with mental ray because with maya hardware I don´t have the problem. I attach some pictures: A jpg of a single frame with mental ray render which looks exactly as I need the animation to look, a top view of my project so you can see my lighting (if it is of any help) and a some screenshots of my render settings, at least the once I suspect may be causing this problem. Apparently I cant attach the tga, and when I open it in Photoshop it looks just black but the point is it looks like no lights are there.
If it is of any use I am using a macbook pro with 8gb memory.
Thank you all.
