Topic: Multiframe Incramental: Good solution for GI animations.

Here is a go at camera moves:

Please use the DivX 5.0 Codec to view.

Render time
Irradiance Map: 20 minutes
Sequence: average 1 min 45 secs / frame

We preprocessed irradiance map with incremetal add to current frame every 10th frame, -4 -3 15 Hsubdivs 100 Interp Samples.

Follow-ups

Q: Excuse my ignorance but, how do I preprocess irradiance maps every 10th frame for use in generating an animation?
A: i think what u do is u set max's render dialog to render every nth frame.
then set vray's irrad map to incremental add then render the nth frames
and once all the nth frames are rendered, u save the irrad map and then use it to render the whole animation.

Q: That method works for me.. BUT isn't the "Multiframe Incramental" supposed to be used for moving cameras? Where is just adds to the previous frame? It doesn't seem to work for me... Am I mis-using it? Is it actually used for something else?
A: Multiframe incremental adds the new bits, and works fine for camera moves. Just remember to start off with a clear irradiance map, becuase it uses whatever is on memory.
