Strange Cycles rendering

Support Lighting and Rendering
#1

Hello. I have the scene with solid fractures of building, lamp “Sun” and “Wind” force field. Sun isn’t animated. During rendering Cycles suddenly begin to render frames as well as lamp “disappeared” and grey “Diffuse” material becomes darker. Why does it happen?

Original scene:

Previous frame:

Next frame:

Here is the link to my .blend file: http://www.pasteall.org/blend/35897.
It begins from 2197th frame. I want to notice that the “Sun” “disappears” when either the second layer or both layers are active. When only the first layer with smoke is active the “Sun” doesn’t “disappear” :).

post the .blend file so we can take a look.

Here is the link to my .blend file: http://www.pasteall.org/blend/35897.
It begins from 2197th frame in my Blender 2.74. I want to notice that it occurs either the second layer or both layers are active. When only the first layer is active, the “Sun” doesn’t “disappear” :slight_smile:

Hmm, your file crashes over here as soon as i go above Frame 2185…

I do think the issue might have something to do with the Volume. You could try if it still happens when you disable “Smoke Adaptive Domain” on Smoke Domain Object.

Nothing changed after disabling “Smoke Adaptive Domain”.

On Object Plane.019 in Particles Tab under Render disable Emitter checkbox.

You buy me a coffee now? (Just kidding)

It solved the problem only until the 2199th frame:confused:.
