ayidi Posted February 13, 2015 Share Posted February 13, 2015 Under the "Mantra ROP Parameters affecting photon maps" section the documentation says the shading limit parameters and allowable paths affect the generation of the photon map. From my testing these parameters seem to have no effect, could someone please confirm? https://www.sidefx.com/docs/current/nodes/obj/indirectlight Quote Link to comment Share on other sites More sharing options...
Jason Posted February 13, 2015 Share Posted February 13, 2015 I think you are right. That might be legacy documentation from an older implementation of photon mapping. Allowable Paths allows caustic light paths to be acheived by brute force, and Shading Limits are for camera rays, not photons fired from Lights. 1 Quote Link to comment Share on other sites More sharing options...
