No idea - how will automatic roughness work with roughness maps (think PBR material)?B.Y.O.B. wrote: Tue Feb 05, 2019 9:06 pm Not yet.
I think the plan was to make this mostly automatic, determined by roughness - is that already implemented?
Ok - Metropolis as expected.B.Y.O.B. wrote: Tue Feb 05, 2019 10:01 pm The photongi settings are defined here: https://github.com/LuxCoreRender/BlendL ... ig.py#L323
Everything not set there is using the default set by LuxCore: https://github.com/LuxCoreRender/LuxCor ... e.cpp#L590
I reverted the plan at the end and only implemented an On/Off flag because glossy roughness can be textured, so it is variable and pretty much unknown (so I can not implement an automatic setting). So, yup, the material flag should be exposed.B.Y.O.B. wrote: Tue Feb 05, 2019 9:06 pmNot yet.epilectrolytics wrote: Tue Feb 05, 2019 8:59 pm Dade added some option to exclude glossy materials from indirect cache, is that exposed somwhere?

It is more the usual problem of power balance between sky (very low) and sun (very high): it looks like photons are fired mostly from the sun. Have you tried alternative light strategies ?epilectrolytics wrote: Tue Feb 05, 2019 8:53 pm First results are quite sobering, caustic cache doesn't like environmental light:
Can you post the test scene ? It looks like a good test case.zuljin3d wrote: Tue Feb 05, 2019 5:48 pm I tried to tweak radius and photon count, but anyway result not perfect.
It requires ray differentials and it would be the optimal solution but, unfortunately, we don't have ray differentials.lacilaci wrote: Wed Feb 06, 2019 5:53 am Could the lookup radius be calculated from normal pass in screen space? So, large areas would have larger lookup radius and when approaching edges it would be smaller, maybe at the very edge no photons just pathtracing? Is this a stupid idea?
Or maybe just somehow force more acurate calculation on the edges and corners...
Changing light strategy or importance doesn't change anything.Dade wrote: Tue Feb 05, 2019 11:40 pm It is more the usual problem of power balance between sky (very low) and sun (very high): it looks like photons are fired mostly from the sun. Have you tried alternative light strategies ?
