question: run denoiser button grey out

[stansu]

as title, and when i finshed viewport render mode, it show "could not start denoiser:[errno 13] permission denied

The "run denoiser" button is only used during final render, not in viewport renders.

when i finshed viewport render mode, it show "could not start denoiser:[errno 13] permission denied

What is your OS?
If you open the folder of the BlendLuxCore addon and then the "bin" folder inside, does it contain one of the following:

• "denoise.exe" (if you are on Windows)
• "denoise" (if you are on Linux) - is it executable?

You could try to remove BlendLuxCore and do a fresh install from the latest release.

i'm using ubuntu 18.04, and i just make denoise executable then it's working!
thanks for your help!

I'm wondering why it was not executable.
How did you install BlendLuxCore? Did you use the integrated updater to upgrade from a previous version?

I use integrated updater

Ah ok, I recently fixed a bug in the updater, it was not copying permission bits: https://github.com/LuxCoreRender/BlendLuxCore/blob/master/operators/update.py#L54
So it's already solved, but we have no way to fix this in existing BlendLuxCore installations.

hey i fixed this problem by giving permissions manually

but when installing it throught blender we still have to manually give permissions

Hi, for linux user find denoise file in addons install directory, open terminal in site and execute the comand in terminal:
chmod +x denoise
