LuxCoreRender Forums

The scene is working fine here. Have you tried to do a fresh PC reboot and just run LuxCoreUI ? Without Blender. Are you rendering the same scene with multiple applications at the same time ? Like Blender preview and rendering or LuxCoreUI ? Normally when running LuxCoreUI I have the file explorer ...

Yes, just tested, same error: [LuxCore][16.234] Saving persistent PhotonGI cache: room+ball.pgi RenderSession starting error: boost::filesystem::rename: The process cannot access the file because it is being used by another process: "252df703-7125-4bfa-9bb3-c80c38efa1ac.pgi", "room+ba...

BlendLuxCore now has a first, rather crude, support for persistent PhotonGI cache file. Thanks for making this available! Trying to use it I get this error: [LuxCore][149.078] Saving persistent PhotonGI cache: C:\Users\me\3D Objects\LuxCore\room+ball.pgi Traceback (most recent call last): File &quo...

LuxCore UI is not bad as it is already (also Fox has demonstrated several improvements). Two things are really annoying (not UI related): - Resize problem. Once a file is opened, its resolution should be applied and rendered. - Autostart problem. Autostart should be disabled by default so that vario...

Thanks for clarification!
I didn't know that silent AOVs are possible.
I thought I had observed OIDN blur without AOVs but that might have been in very early stages before background activation was introduced.

With albedo and average normal AOV activated OIDN shouldn't make anything blurry.
But in my Blender OIDN is on by default but the AOVs aren't which can result in blurred textures.

@peperepe77: Great render!

2, Manually setting both the Lookup radius and Brute force radius scale parameters reduces 95% of flickering (manageable level) Sounds good! Another, simple interior animation: There's some visible flicker, especially on the furniture, looks like doable with better cache. But then for this kind of ...

Property debug printing can be enabled by searching for the "debug" operator in Blender, then enable the "Print Properties" option: Sorry for being stupid, but where is the search field in Blender ?? :oops: There is a python console, but without search field. :? Instead I conven...

Yes it is an old scene made with an earlier PGI version when there was no automatic setting and it was likely used to export binaries too.
But when I reopen it in current Blender I expect the new defaults to be exported correctly

Why are you setting the values by hand ? Because of B.Y.O.B.'s suggestion: It might be possible to reduce the bias to the point where you don't notice any flickering. For example by using a smaller entry radius and/or raising the brute force radius scale (aka usage threshold scale). Just use automa...
