PhotonGI cache

[Dade]

btw regarding caustics, do you think that you could cache reflective caustics too? Maybe bellow certain roughness, opposite of indirect cache...

What do you mean exactly with reflective caustics ? What is the difference with normal caustics ?

Well I guess the normal caustics are the specular ones, like through glass etc and I call the reflected ones the ones from highly reflective material, metals etc when no clamping is applied. Atm the caustic cache works with specular materials only, no?

Like I disable indirect cache for glossiness under 0.2, I could enable caustic cache in the same situation

However be aware that caustic cache is a lot more complex, slower, etc. to use than indirect cache (because it is seen directly).

Yes, at the moment.

I added the support for caustic cache to OpenCL code.

Thanks. Awesome!

Cache filtering is a setting that needs an update to the Blender Addon?

It has not yet been added to BlendLuxCore but the default value will enable it if you update the binaries.

PhotonGI indirect cache now supports all not TRANSMIT and not SPECULAR materials (i.e. metal2, cloth, mix, glossycoatting, etc.).

That was quick, will try on thursday. Now shooting wedding

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 with caustic, i can set lookup radius to any value, like 100.
Indirect cache can have lookup radius at any value, under opencl or cpu
My computer have 4 core intel cpu, nvidia 1060 6gb.
