prepass calcs. when rendering

[proces2]

I am rendering out an animation. the irrad. map is created using multiframe incremental. when i then rendered a scene where there is only sunlight and skylight - it worked just fine.

now, i have the same scene but a bunch of interior lights. same process - create multiframe irrad. map - then use saved irrad. file when rendering.

but, now what happens when rendering is it goes through the "prepass" calculation again for each frame. it doesn't spend as much time doing the "prepass" calcs. as when i was originally created the multiframe irrad. map, but it certainly adds about 3-5 minutes per frame.

is there a setting in some of my interior lights that is causing this to happen? is it changing the irrad. map when it does it at each frame - ie - will it cause flickering?

Are you using a 1.09.03x build and interpolated glossy reflections/refractions?

If so, the prepass is calculating the reflections/refractions only, and is not affecting your irradiance map. The glossy effecs have to be calculated for every frame because they are view dependent.

yes on both counts.

thanks!

there are only a couple objects that use the int. glossy reflection. what settings can i change with the material to speed up that process?

In the "reflection interpolation" rollout, lower the min and max values. You can also increase the color threshold. Of course this will also reduce the quality, so find a setting that works for you.
