caustics cache not working on glossy translucent/matte translucent materials
I have been facing an issue with the caustics cache. The caustics show up through glass when reflected off of a matte material/disney material/maybe others. Caustics do NOT show through glass when reflected off of glossy translucent/Matte translucent material. I will attach the blend file also.

At the moment, PGI doesn't deposit photons on: https://github.com/LuxCoreRender/LuxCor ... he.cpp#L68
Translated, photons are not stored on surfaces that:
- transmit;
- or specular;
- or glossy and under the glossiness threshold;
- or have PGI disabled.
I can look if I can relax the "transmit" constraint (i.e. your problem).
