It seems that I can't get pretesselated displacement to work in Maya 2012 (I haven't tried in Studio, as I don't use it).

Here is what I get when using the "old" (on the fly) setting :



But when I switch to pretesselated, I get this :



As I have said so many times in the past when fiddling around with 3D, "I must be missing something, but what?"

Are you using a greyscale TGA? Could be this bug:

If you just change it to RGB instead you should have the same render.

I am using a TIFF32 file, but here too switching from Greyscale to RGB did the trick :



Rendering is indeed faster that with the "on the fly" method, but eats up a lot of memory. The height of the displacement isn't exactly the same, but that's no problem.

Definitely a great addition!

Yup, with pretesselated you have to be careful with the subdivision setting as all triangles created before rendering and kept in memory. With each subdivision it doubles the triangle count so it's an exponential increase of triangle count.

With RAM being now so cheap (I just bought 24 GB for $215), pretesselated displacement is a very good trade-off.
