Thanks for the replies.
cgbeige, I can’t try rendering it because maya doesn’t actually load the file into the node. I’ll try exporting from Photoshop and playing around with the compression settings to see what I get. I’ve read previously though not to use LZW as mental ray doesn’t like it either.
refract, I’ve used 16 bit plenty in the past however really wanted to try 32bit because they are supposed to contain more information and give a much better result.
I was using a vector displacement map which was giving really good results but the problem is that vector displacement at the moment doesn’t support animating deforming characters (at least to my knowledge). Even though Zbrush has a setting for tangent space vector displacement, I can’t seem to get them to render in maya at all.
Does anyone have experience with VD maps?
