Introduction to Maya - Modeling Fundamentals Vol 1
This course will look at the fundamentals of modeling in Maya with an emphasis on creating good topology. We'll look at what makes a good model in Maya and why objects are modeled in the way they are.

maya and displacement maps

after days of fighting with this (countless crashes thanks to a somewhat lacking integration of mental ray) I finally had a little breakthrough yesterday.

note that this head is a pure poly model with just under 5000 polys (I tried with SubDs before, but that only crashed... I already logged that bug with Alias). I used the mental ray displacement approximation to tesselate it at rendertime to allow for all the fine detail.

here's the screenshot:

PS: no textures, no bump maps or anything; just pure displacement. rendertime under 2 minutes.

very exciting IMO

here's a closer shot at higher rez.
this one rendered in under 4 minutes (!!)

(hint: tweak your BSP depth in the mental ray render globals, 40 seemed to be a sweet spot for this particular scene).

notice the fine detail around the eyes (the bad skin courtesy of me going overboard with the noise on the displacemet map user added image ...bleh; it's just a test anyway)

MR is rendering that pretty fast. Good deal. btw what is the speed of your computer anyway? would be usefull to get the idea of the full afect of the render time.
