Relight Surface Map Just Black

Hello,

I'm not sure why, but Relight seems to either consistently crash or just not work. When it fails it looks like this.

This is a rendered in place ProRes 4444 image. It also typically fails when I go direct to the fusion keyed source.

Currently, I have not been able to get it to load at all for this shot.

I have caching turned off. It seemed to fail more often with caching turned on before.

Hard to say.

Does anyone know how to fix this? I have a deadline and need to use Relight.

Thank you in advance!

You have two problems:
1) The Relight Map Preview box is ticked.
2) The input is set to Input 2, yet there's nothing in Input 2.

See page 3387 in the February 2025 Reference Manual DaVinci Resolve 19.1

Hey thanks for the reply.

In that example, I had made that mistake. Normally, with the surface map setup, it works. But even after properly connecting that one, the surface map didn't output correctly.

When using it standalone without a surface map, it would regularly crash and output only a black screen. Causing me to have to restart Resolve to get it to start working again.

Appreciate the quick reply. Apologies for sharing a dumb screenshot.
