Hi,
is Mental Ray the way to go for lighting? Has anybody used it yet?
Thanks,
Ray Shingler

mental ray has nothing to do with lighting...
just rendering quality...and the renderer type...
lights have to be setup by you anyway...and if you cant do it with the standard renderer..then mental ray wont help...
also..mental ray is very expensive....

Check this site to see what mental ray can do with the light:

Hi,
I'm looking at mental ray for Architectural renderings (mostly interior)where more acuracy is required. i think it will save me time as compered to the 3ds Max renderer

I used mental ray renderer... but It doesn't deal with light but with quality of rendering... also, it will kill your machine if you want to produce mid-class quality (takes hours per frame) how about high-class quality (may be days per frame)... I don't want to disappoint you but this is the case.

Hi, been testing mental ray for a while (have a license together with max31.
I was tired of the 300 lights in my max scenes to get almost that look. With MR i get it almost with 1 lamp.
Problem is the overexposed energy bounce (floor greyed, but ceiling double lit. (impossible! dif and spec refl at 1 or 5!!) and major block-like artifacts. Last test took 66hours on 2xP500.
Will put tests on page when ready, mail when intrested.

Hi,Wim De Boever
When I do architectual renderings for corporate interiors I too have to install alot of lights. It's very time consuming. But it sounds like you spend less time with setting up lights but more time rendering, even for test. Is that correct?
Thanks, Ray

Also, Jeremy Engleman has been doing some very interesting studies to dodge using GI and Radiosity renderers. They're done fairly well!

http://www.maiden.org/jeremy/illuminations/index.html

They arent nearly as accurate as using MR, or Messiah:Render(arnold)
I'll use these techniques before I go out and spend that much on Mental Ray.
