Re: Interrupt Async Imagepipeline

It may be a lot easier to just write .pfm file from python once you have got the RGB buffer from LuxCore and read back from the new .pfm format the results. PFM is a trivial file format to write/read: http://www.pauldebevec.com/Research/HDR/PFM I tested this and I get about 45 milliseconds to write...

Re: PhotonGI cache

In my main 3D app Cheetah3D this problem doesn't exist and whenever I port an interior scene with sunsky into Blender I have to put it into a Box for shielding, and the box has to be black or light will even leak through solid double geometry walls! Maybe the issues come from the export/import? For...

I don't have the "visibility map done" line, don't know what that does or if its related to the GI cache?
No, it's just the "automatic portal" that is used for environment lights like sky or HDRI, if you don't have such a light source it is not computed.

Re: How to do HDRI invisible to the camera?

You could use the transparent film option in the camera/imagepipeline properties.
The HDRI will be transparent and you can place what you like instead in the compositor, with alpha over node.

Re: PhotonGI cache

I can reproduce the crash with glossy default cube, Path CPU + PhotonGI, on Windows. The terminal log ends with: [LuxCore][2.313] Visibility map done in 0.16 secs with 1000000 samples (6.41M samples/sec) [LuxCore][2.328] PhotonGI trace visibility particles thread count: 16 [LuxCore][2.500] PhotonGI ...

ohohho.... now we should wait BYOB for using GPU with PGI on Blender...is it right?
No, there are no changes in BlendLuxCore required to run it on the GPU.

edit: I have exposed the normalangle parameter.

Re: Translucent material (a sheet of paper) with an image texture?

the problem is that your texture is completely white (1), while my texture is grey in the bright parts. This means your texture reflects ALL the light in the bright parts, so nothing can be transmitted. But in the darker parts (the text), not everything is reflected, so some light can shine through,...

Re: OpenImageDenoise

Yes, noise in the albedo AOV essentially disables the denoiser in those areas. Let's see if noise-free reflection/refraction in 1 sample can be implemented in LuxCore (I asked here ). If not, it might be a good idea to drop the reflection entirely (in the albedo AOV) or prefer reflection/refraction ...

Re: PhotonGI cache

The normal threshold is not exposed in BlendLuxCore. Should I add it, is it needed? Or is this just a very rare pathological case?

Re: Translucent material (a sheet of paper) with an image texture?

Did you plug the texture in both reflection and transmission color?
