Re: UE4 for archviz test demo

I did some smaller archviz presentations for a client before and like Sharly said it is quite time consuming for an individual. It can provide really good gi but it has to be baked per object into lightmap and you also need to have good quality and non overlapping UVs. But it is far superior to any ...

Re: WIP PGI DEMO

I'd also like to know what is glass2? Also, can we have option for materials to pass through photons/diffuse in general?

Re: WIP PGI DEMO

Cycles has these options per object! Screenshot from 2019-04-04 12-50-55.png vray, corona, cycles, even maxwell! has options like that to boost performance with complex objects like glass panes etc. With cycles I disable diffuse, glossy and shadow options on object and I get glass that on camera loo...

Re: WIP PGI DEMO

Using archglass is a terrible idea, it never looks good (aside flat panels like in a windows in distance). It would be much better to have an option for object to let gi go through.

Re: Laci's wip

I can get the behavior much closer now but since much of the scene is directly lit with sky through windows there is a lot of noise in luxcore. I think cycles's portals do much better job than auto visibility solution of luxcore. luxcore Screenshot from 2019-04-03 17-09-29.png cycles Screenshot from...

Re: Laci's wip

Very interesting.. So I've figured there was a shading issue, autosmooth + bevel modifier changed shading and that resulted in the error. The interesting part is that this type of shading issue doesn't seem to affect cycles at all. This is frustrating So was it normal interpolation related ? seems ...

Re: Direct Light cache: how to avoid splotches?

I'm also not happy of PGI caustic cache. Me too, but I think it is not urgent. Maybe better to take a break from it, read some more papers and wait for some ideas. From what I gather users want now: - principled shader - 2.8 Luxblend version - PGI animation I'd suggest to implement PGI animation, f...

Re: Laci's wip

Can PhotonGi benefit from importance sampling from grazing angles? If you have surface like that: Surface like that.png Viewed at this angle View Angle.png It tends to render black, no matter what material. I don't know about photongi, this issue was present before photongi.. But cycles can avoid m...

Re: Laci's wip

I understand. And I hope at 2.3 this issue can be somehow resolved. Anyways, in cycles I used their principled material(used very glossy values aswell!), I use it for anything as there is no reason to use different materials. It never fails to provide good reflections at grazing angles, the only 2 m...
