Hi,

I'm reading about GI and caustics. My book is written for maya 5, but I'm working in version 6.5.

In the caustics and global illumination tab in the ligths attributes, there shuold be a checkbox called "physical". But I don't have it.

Where is it now and what is the reason it have been moved?

Thanks,
Jakob

Hello, no need to use physical light , use the decay rates, now it works fine with mentalray :)
