View Full Version : Displacement maps and Maya's renderer
04-19-2005, 06:50 AM
Recently I was told that do to licensing restrictions I have to use Maya's renderer to output a quadruped for a feature film that is highly displacement driven apposed to using MR. The character is 27,733 unsmoothed and smoothed it's 107,786 and I am using 4k maps. Unsmoothed I get a result from the renderer, a very ugly result but still a result. When I smooth and render Maya throws the low memory error that we all know and love. I have tried a few techniques from you great people on this board but still haven't found something that works well. Should I be leaving featured displacements on or off? Does anyone have an idea of a successful workflow for using the Maya renderer on a character such as mine? I am gratefully accepting any suggestions. Please help!

i think 'feature displacement' is something that you should be leaving on; i was playing around with trying to get some different effects from a displacement last night and while reading through the included help file (which is very helpful by the way), i remember reading something about feature displacement cutting down on render times and being nicer to your computer in terms of memory and whatnot. Apart from that i have little to no advice for you, im having some major displacement problems myself actually. Anyway if you haven't already, i highly recomend checking out the included help file with maya; it explains feature displacement and all the options below it. good luck

Feature displacement utilizes adaptive tessellation which is VERY memory intensive. Besides you should be using mental ray not Mayas crappy renderer.
When you are rendering are you using the internal maya render window or are you trying to batch render. Because I have a similiar problem with my thesis, the model is really light too but when i put the displacement map on it for text it goes nuts. I have to render a single frame or multiple frames as a batch.
I am guessing this isn't in your pipeline, but I was getting faster results from using Nurbs over Poly models for displacement. But like I said my model was a torus not a character model.
This is a little off topic, but I remember reading somewhere about zbrush, and it mentioned having feature displacement turned off for characters when using maya's render.
I hope I didn't ramble too much, 2 and half weeks til my thesis is suppose to be submitted and about 2 months worth of work to go.
