CUDA render error

When rendering with cuda I get horizontal stripes in the picture. The last two versions of BfA have this error. This does not happen in Blender Beta.

Indeed, not nice. Thanks for the report. I'll investigate into it.

EDIT, i cannot reproduce the problem here. Could you please provide an example scene that fails for you? Does this happen with CPU, GPU supported or GPU Experimental?

Issue is here: https://github.com/Bforartists/Bforartists/issues/588

I have uploaded a new dev vesion. There went something wrong with the merge. Means the dev version from sunday was basically nearly the one from last week.

Maybe this fixes the problem already ...

Thanks. But when you save a scene then you save some settings with this scene too that could probably help me to find out the cause. I can still not reproduce the problem. GPU rendering with denoising on, and it renders just fine. Ah, bug hunting.

Another thought, and thanks for your patience, but could you reset to factory settings and try again? Smile

Ah, the attachment was hidden

Ah, the attachment was hidden. You have to tick display for uploaded attachments. I haven't found how to do that by default yet, unfortunately.

Testing the file ...

EDIT, renders still fine. Hmm. Running out of ideas. One last thing that i could try is to download latest Cuda version, and compile with that version. Give me an hour ...

Just curious, how old is your graphics cards driver? Have you updated it recently?

Looks more like a driver error than a problem with BfA-if it is not reproducable? Did you try updating the graphics drivers to the latest version?

I have a 1050 GTX card, he has a 750. That's a completely different shader model. So it says nothing that i cannot reproduce it here. We would need somebody with also a 750 card. It's stumbling in the dark at the moment. All i can do is to exclude everything possible at my end, and hope that it fixes the problem at one point.

I have a 750ti as a secondary graphics card, never had a problem with rendering in BfA with it.

When I was a tester for Thea

When I was a tester for Thea that result was low GPU memory or overheating
I have a cr*ppy Quadro 600 so its very unlikely to work with denoising

Personally I'd be runing Asus GPU Tweak and see whats happening
