Re: PhotonGI cache

so apparently, bump mapping is still killing cache for me. EDIT: I'm actually not sure if it's bump or something else, but I couldn't figure out what is going on... everything is mostly black The smell like floating point NaNs (i.e. Not a Number, like the result of a division by zero, etc.). I will...

Something to suggest?
It is this bug:

See the border on the glossy material ? I have the felling it is due to cached paths not including the light emission, I'm looking into the problem.

Re: PhotonGI cache

I have introduced a new stage in PhotonGI caustic cache pre-processing. It merges near photons coming from the same directions. This allows to greatly reduce the number of clustered/overlapped entries in the cache and to greatly improve the rendering speed (especially for larger radius). This is a r...

Hopefully you wouldn't need to and this option should not be exposed in my opinion...
Ok, thank you.
It a safe net if something is not working well. It should be never required (but it is better to have it as last resort).

So, I assume, it's something with my settings.
Can you post a test scene causing the crash ?

Re: PhotonGI cache

Hey, I have the same problem with latest benchmark scene for Luxcorender 2.1. While using cpu only it's working, on opencl it crashes Blender in the same way. I'm using GTX Titan Black. I had a similar problem with LuxCoreRender v2.1 benchmark scene with an older NVIDIA driver. Have you tried to up...

Re: PhotonGI cache

For a test scene, I tried to make the caustic result look smoother so I increase lookup radius. I found a problem. using opencl + photonGI, setting caustic lookup radius higher will crash blender. The error message is "ERROR: clEnqueueWriteBuffer Error: Unrecognized Exception". Path cpu works well ...

I have instant crash when I try to render any scene with caustic cache (path CPU).
I have 8 GB RAM. Maybe it's low RAM related?
Does it happen with any scene ? For instance, including the one posted above by B.Y.O.B. ?
