When I IPR render a frame the Lights seem to disappear whenever I change to the next frame (or any other frame for that matter. Going back to the previous frame doesn't show then again. It's as if the are unloaded from the GPU. Only the Sun/Sky remains.

I've just rendered a few sequences over night and the same thing seems to happen when using the batch render. I'm rendering on 3 machines and they all have the same issue but not all the time. I'm rendering chunks of 20 frames. Sometimes all goes as expected but in half the cases only the first frame is properly lit and after that only the env sun sky remains. The animation mode is set to movable proxy.
I'm going to try if setting the animation mode to full helps but would rather not as this doubles the rendertimes!

Thank you for report. I will check it.

I'm on 2.20 61

somewhat reluctant to change version during production, but I will do so if you recommend.

I can't reproduce it, at least in recent 6.4 version. Could you give me the scene where it is reproduceable?..

I'll have to look. The project is under NDA but I will try to strip the scene so I can send it. Might take a few days. Bit busy trying to finish the project.

I had the same issue this days, what I did I just replace the light by a mesh and apply a shaders with octaneTextureEmission on. and is work.This may help you now.

I have somewhat same issue in Cinema 4D, First frame in an animation I render out is properly lit. The frames that follow are a lot darker. So I'm guessing the problem is not a plugin issue.
