Hi - a bit more involved question this time, hope someone can help. I'm building a scene which is going to be rendered full-animation GI, with a rather tight deadline, so I'm on the lookout for techniques to build the prepass caches more quickly, if that's possible, and get the thing rendered without any nasty surprises - was wondering if anyone had any tips about this.
The animation is mainly camera animation, in that the camera moves around a room pausing (never stopping) at four or five stations, where fairly detailed animations take place.
I'm using the R14 radiosity maps, physical renderer + depth of field. IR+QMC (Full Animation). Current render time is around 4mins per HD frame.
Some of the tricks I've learned using VRay are to render the prepass with lower resolution, and skipping frames - is that possible/recommended in this case? So say my final result is 500 frames, full HD; can I render the prepass at 960x540 and skipping every other frame, then lock it and jump back to full res? Or will that cause problems/errors with the GI?
Last complication, the scene is going to be stereoscopic, so I'm hoping to render the prepass once then render the two eyes using the same ilum files - any pitfalls here?
The manual is pretty thorough in describing the functions of each aspect of the renderer, and the tips are good too, I'm running some simple test files now - but the I'm hoping there's some good experience out there as to how to best work with the new options.
Thanks for any advice - Chris
