I already posted this over at xsibase, so I figured I’d post it here too.
This is a short videotutorial on setting up displacement (using a publicly available example ZB3 head obj and displacement tiff texture) in XSI so that it renders very very fast and looks great still.
[size=2]This goes out to those who are under the impression that displacement = eternal renders. That shouldn’t be the case.
I should note that although “View Dependant” is generally a good idea in most cases as it optimizes based on the camera’s distance to the character, if you see artifacts when you get really up-close, just toggle it off and that should fix it. (Of course, it’ll be just a little bit slower… still pretty reasonable rendertimes though.)
Last but not least, if your character needs even more detail, instead of subdividing it more under the Polygon Mesh tab of the Geometry Approximation property, I recommend you just crank up the “Max” attribute under “Subdivision Limit” (Displacement tab)… it’s more efficient this way.
If you already know this stuff, then good for you. Some people don’t know and I hope this will help them.
Any constructive critiques welcome.
