We're currently producing a feature, using maya and MENTALRAY STANDALONE. To keep the sanity of our renderwranglers, and to keep the logistics of rendering reasonable, we've been exporting and rendering .mi files with multiple frames in them. However, with heavy scenes, the time it takes to skip through the frames that mentalray should NOT render is far too big. For instance if we have a sequence of 119 frames, to get to render frame 119, mentalray needs to skip through the first 118 frames..which can take up to 1 hour and 20 minutes. Effectively giving us a frame time for frame 119 of 1 hour and 25, since the rendering itself happens within 5 minutes or so...which is needless to say an extremely huge waste of cpu time.
Is there something we can do, something we missed in the commandline options?? Short of exporting and rendering single frame .mi's, which could turn into a bit of a logistics headache.
Thanks in advance
