Anybody else seeing their render turn a very Houdini-esque shade of orange w/ the denoiser? Mint 18.3, GTX 1060/375.66



I'm baffled… logged as bug #91983, but curious if anyone else has seen this.



Thanks!

I've seen it on my workstation equipped with a Quadro K4200.

I think it is caused by an unsupported graphics card or driver.

I had success with GeForce 980Ti on Windows 10 with driver 416.16

Are you able to test a 390 series driver?

Aha that was it, jumped up to the 384 series fro in the repos, and it worked. Should have tried that first.

Thank you!

I have to bump this thread because it's happening to me too. I tried different graphic drivers but it stays the same. Curiously, it started happening all of a sudden. it was working fine and then it didn't anymore.

Also, it is telling me: “Error: Outdated OptiX version (expected 5.1.1, found 5.1.0). Please re-download OptiX Denoiser.”, which I did, but it keeps giving me this message. I tried manual download and adding the path to the ENV file, but nothing changes.

OptiX is still working when I select it on the Pixel Filter and render to disk.

The only thing I have left is going back to previous Houdini build… but what's the point of that.

Right now I'm in 17.0.459 with a GeForce GTX 1080 ti driver 417.71 (tried 4 previous releases).

While I was in Houdini build 17.0.416, it was working fine.

Any help will be greatly appreciated.

SOLVED

I have uninstalled Houdini (17.0.459), including the folder it creates in Documents, reinstalled (same version) and then “re” downloaded OptiX from the Render menu.

This solved the problem for me… hopefully it doesn't happen again.

Cheers!

I'm having this problem as well, re-installing hasn't helped. Anyone know anything else to try?

Did you deleted the folder it makes in your /user/documents (or equivalent if a different OS)?

That made the trick for me. Reinstalling alone didn't.

Good luck!

Delete the houdini 17 folder? No I haven't tried that. I will I guess. Thanks!

Houdini 17.0.459 appears to be working with OptiX 5.1.0 instead of 5.1.1, even though the render view shows an error (“Outdated OptiX version (expected 5.1.1, found 5.1.0). Please re-download OptiX Denoiser.”).
I don't know if it's the Touring architecture or something else, because it happened to me right after I added a RTX card in my PC.

Here's the download link for version 5.1.0:

Just let me know when you've downloaded it so I can remove it.

Optix 5.1.1 is incompatible with Turing/RTX cards, so it was rolled back to 5.1 since 17.0.464. If you install this (or later) build, you won't see the “outdated version” warning anymore, and the “Download OptiX Denoiser” in the Render menu will link to 5.1.

I had installed a trial of Redshift and this caused the problem.
Might have been something to do with the environment variables I had to add.
As soon as I commented them out again the orange renders using OptiX went back to proper renders.

Thanks @stevegreentechy! I had to disable my Redshift demo too, to get rid of the orange screen. But once I did that, optix seems to work.
