Thanks for the clarification Juanjo. I just got confused by the manual "As an example, if a user intends to render an animation at 24 frames per second and has assigned 24 frames per file using the UI, then this setting effectively means that for every second Octane will load the next volume and render it". Anyways, it doesn't matter, I just wanted to make sure I wasn't missing anything.
another question. When I did a batch rendering for a vdb seq. I noticed that octane reloads each file (frame). So as long as each file can fit in my GPUs, I can render as many frames as I want right?
