irradiance map

I must have don something wrong. i am doing a flyover animation and rendered every tenth frame to get the vrmap, but instaed of one map for the entire sequence, i have a map for every tenth frame, so i have a bunch of maps. What do i need to select or deselect to get the single vrmap as it is in the tuorials (which seem to be e bit out of date when trying to use with the latest vray).
thanks.

You have probably selected the “Animation (prepass)” mode; for fly-through animations you need the “Multiframe incremental” or “Incremental add to current map” modes.

Oh, i did set it to animation pre-pass. I’ll set it to incremental. (What is the animation prepass for?)
Thanks

It’s for moving lights/objects in a scene. It blends the irradiance map together with frames around it to smooth the result.
