animation prepass problem

If you decide to use Embree then you should install it on all render nodes.

About the splotches over the window blinds, I managed to replicate the result you have posted.
Actually this happens due to the lack of GI samples in that area. I see that “Use camera path” option for the Irradiance map engine is enabled, which is not recommended when you are using Animation prepass/rendering mode. It is useful for cases where you need to recalculate single vrmap file for short camera movement only. So try to run another tests using “use camera path” option only for the Light cache and also increase the Irradiance map “Interpolation samples” parameter (at least 14 ) for the final render stage, because “5” will be not enough to get smooth GI interpolation between the frames.

The Irradiance map calculations will become faster using this setup.

1) After i install Embree to all the render nodes, do i still need to install Embree on my local pc?

Just to double confirm the animation prepass set up:

A) set IR to primary, uncheck “Use Camera Path”, HSpd:50, Interp.sample:14,Mode: Animation Prepass
B) set LC to secondary, check “Use Camera Path”, Subdiv: what i want, Sample size:0.02, Scale:screen, Mode: Single frame.
C) leave everything as default ( or do i need to set DMC sampler, noise threshold and etc?), click render.

After calculation finished:

A) Set IR to primary, HSph:50, Interp.Sample:14, Interp.Frame:to what i want, Mode: Animation Render
B) set secondary to None.
C) Leave everything as default ( or do i need to set DMC sampler, noise threshold and etc?), click render.

Is it correct?
