Render output black - urgent!

[kopperdrake]

Hi guys,

I have an old v3 scene that I'm trying to re-render, but I've updated to v4, and IPR, F9 and F10 all show the scene as it should be, but the final output file is all black!

This is urgent for this morning - any ideas?

I know I'm answering my own question, but I've found part of the problem - the denoiser is wiping the RGB channels for some reason. If I render without it then all is fine. If I render with it, I can see the render briefly, but then that is overwritten with all black in the preview window.

I'll look into it later, once the render is complete.

Hi,

Are you working with the PMC kernel? This kernel is not compatible with the denoising feature, and the rendering is always a black image.

Thanks,
