Topic: Caustics: Inverse Square Falloff 101
posted by MIKE_KENNEDY
archived on 29.5.2002
After pulling my hair out with Caustics I found a neat trick. I haven't heard of it from anyone else so I will post it here with an example file.
Basically what was driving me nuts was having to use Inverse Square Falloff on my lights. I hate using it, prefering to contol my attenuation manually. I noticed you could change the start distance on a your Max lights when working with inverse fall-off. COOL!
THis means I can have the falloff of the light start BELOW my ground plane so I can leave my Light at a 1.0 multiplier but still use BRIGHT cuastics. To pump up my caustics I increase the multipliers in the Cuastics area of the VRAY rendering Rollout and in the system area. I also make sure I turn off SEND CAUSTICS in the system area EXCEPT for what I want to send and what iI want to recieve.
IT make a diffence form what I can tell. No manual, so I am guessing...
Anyways, suddenly I am getting BE-U-TIFUL caustics. I used to think FR did better caustics, but thats something I am GLADLY wrong about.
(Sorry for shouting, but it's late and I can't jump around, I will wake the building ;) )
Anyways, here is that FR Forum wine glass. Improve it all you want, jst let me know when you have smoked in quality wise, I can always use a new trick or tip...
