goldleaf Posted September 1, 2016 Share Posted September 1, 2016 Very cool, looking forward to using it when I get some time! Quote Link to comment Share on other sites More sharing options...
tamagochy Posted September 20, 2016 Share Posted September 20, 2016 In dielectric mode some weird result with reflection roughness. 0.01 roughness makes light totaly blured. I use skylight for testing and its not possible got normal reflection from the sun. Quote Link to comment Share on other sites More sharing options...

I use skylight for testing and its not possible got normal reflection from the sun. I got this with skylight (PBR, diffuse disabled). Also, I recommend to use Environment Light in Ray-Tracing Backround mode, not direct lighting. Quote Link to comment Share on other sites More sharing options...

rsd Posted September 23, 2016 Author Share Posted September 23, 2016 The sun light is not properly sampled. It's a problem of light shader, not surface shader. Probably SESI's MIS scheme is't efficient enough. There are results of various sun angles, brightness is changing non-lineary. phyShaderTets.hip Quote Link to comment Share on other sites More sharing options...
angelous4x Posted October 12, 2016 Share Posted October 12, 2016 Hey Roman this could save my ass, trying to do a diamond shader with dispersion. i think your tools could help. but not sure how to install it. can you help me out. thanks Quote Link to comment Share on other sites More sharing options...

nigelgardiner Posted February 22, 2017 Share Posted February 22, 2017 Hi Roman Thanks for Physhader, it's great, esp nested shader capability. One question, can I have a nested shader inside a nested shader? For example I have liquid shader as the nest for air bubble shader and then glass shader as the nest for liquid shader? I see I get an error warning when i assign the nested liquid shader as the material for the glass nested shader but I see something is rendering out so not sure, maybe it works? thanks again Nigel.

rsd Posted February 25, 2017 Author Share Posted February 25, 2017 Hey @nigelgardiner. It should work, but I'm sure that it's not necessary (at least until the bubbles are not too big or are situated at the liquid surface). The usual PhySurface material is enough, just swap IOR on bubbles material: Outside IOR = liquid IOR and Inside IOR = 1. And nevermind that warning, it rises because the script can't find some PhySurface parameters on the nested material to link. All remained parameters can be linked manually.
