Vinz 7 Posted February 6 Hi Odforcers, does anyone know how to wire the 'fake caustics' VOP inside mat builder? (apart from using the principled shader, tx) Share this post Link to post Share on other sites
schwungsau 281 Posted February 7 not sure how do it in mantra work. but with a regular pathtracer, you take the dot product of surface normal (N) and the in-coming rays (I) and plug into a ramp and feed the shadowcolor with it. Share this post Link to post Share on other sites
Vinz 7 Posted February 7 Very nice stuff man! Do you think you could give it a shot? Here is a tiny test scene with the mat builer https://www.dropbox.com/s/gmry1m5c49btb1l/Fake_Caustics_VOP.hipnc?dl=0 That would be very useful to me on the long run..

Nicholas Ralabate 20 Posted February 7 I think you just pipe it into opacity... crack open the Principled Shader Core to see how SESI sets it up... ncr_fake_caustics.hiplc 1 Share this post Link to post Share on other sites
