schmoron13 Posted August 15, 2003 Share Posted August 15, 2003 Am I missing something about photometric lights? I'm doing my first remodeling job (redoing my mom's kitchen) and decided to try using photometric lights to simulate what it'll look like. I have about 16 photometric lights, and it's KILLING my rendering. It's taking about 11 minutes in 3ds max with only a base/generic material and that's using vray free with very low rradiance map set to very low (hsph subdivs 30, interp samples 10) here's what the model looks like ("quick" rendering)... what am I doing wrong with photometrics? :???: Link to comment Share on other sites More sharing options...
proces2 Posted August 16, 2003 Share Posted August 16, 2003 with your subdivs and interp samples comment - i am assuming that you are using VRAY. in the vray forum, i asked a similar question. apparently, when using some IES files, it can considerably slow things down with vray, but with others it can work just fine. there doesn't seem to be any determination as to which are problematic and which aren't. i had problems when using an IES file on a linear light.

starr Posted November 14, 2003 Share Posted November 14, 2003 I believe that for photometric lights you have to have a closed space, like a box with inverted normals. Also, you should mix them with nonphotometric lights... Starr Link to comment Share on other sites More sharing options...
