Re: OpenCL+Metropolis won't render

I see... maybe the new caching could make this renderable though. Maybe, but all the photons that shine through the glass will end up in the caustics cache and will probably still be harder to trace than direct/indirect photons. The problem with archglass is no refraction. For thin window glass (a ...

Re: OpenCL+Metropolis won't render

You'll have to set the glass to "architectural" so direct light can pass through.
Otherwise, all light passing the glass is caustics, and those are obviously very hard to render for unidirectional path.

4. How hard would it be to also add this feature to Blender API?
What exactly needs to be done from the Blender side?
Create a list of points on the surface of a mesh, and write it to a text file? Or something else?

Re: A Few Suggestions For Awesome Lux Developers

-attribute node (I dont know if there already is one but it is very helpful for multible uvmaps) LuxCore currently does not support multiple UV maps, but when it does, I would implement something better than this lazy attribute node. Probably a dropdown list of available UV maps. -Color ramp (more ...

Re: PhotonGI cache

I think the need for this depends on how much trial and error is involved to find the right settings for the PhotonGI cache. If you need a lot of trial and error, starting 10 renders or so until you found good setttings for photon count, radius etc., then it would be very good to have this pre-visua...

Re: PhotonGI cache

Is it possible to show this while the cache is building, then switch to normal film mode when the render starts?

Re: OpenCL+Metropolis won't render

Metropolis is a much more complex sampler than Sobol or Random, and on the GPU it consumes more memory (because there are more cores, and each core needs a copy of the sampler).
The scene probably fits barely in memory without it.
