This course will look in the fundamentals of modeling in Maya with an emphasis on creating good topology. It's aimed at people that have some modeling experience in Maya but are having trouble with
complex objects.
The 3 minute render, was that at the size that you posted?
If so, did you only use final gathering, or did you use a mix of GI and final gathering. A mix of GI and FG gives a much greater approximation of bounce light/colour bleeding than just final gathering or GI by itself. Also, just as importantly you can get much quicker render times using the mix as the final gathering is used primarily to 'smooth' out the rough but quick GI solution.
Here is some images that I rendered with mental ray tonight.
My machine is a P3 450, not the sort of machine that you would hope to batch render GI stuff in.
The first two are using just a single spot light.
Time to render 1 minute
Spots are good for Photon use because unlike point lights that throw light and photons in all direction spot lights concentrate the light and photons in a single direction which means faster renders.
the middle image (same as top left) but with GI turned on.
Time to render 3 minutes
Settings are:
Spotlight:
Energy 180,000 (all channels)
Exponent 2
Physical Yes
Area lights turn "Off" (Unless you want excessive render times).
Mental Ray render globals:
Global Illumination tab:
GI accuracy 800
Gl radius 1.35
One is from xsi base but the principles apply to Maya to mental ray as xsi uses mental ray as it's base renderer. As far as speed goes I have rendered the same scene in both maya and xsi.
This is some awesome information gathering for mental ray. I thought I'd add a link that helped me with some of my settings. I'm getting some very nice renders with the settings suggested here (fast renders too) https://www.steven-tubbrit.pwp.blueyo...utorial_02.htm
