Heres an awsome overview of using ZBRUSH with mental ray if you need it: https://206.145.80.239/zbc/showthread.php?t=025542 Keep going, dude! Thanks. I've read that thread.. awesome thread agree. I watched the video and it helped me get stuff set up in mental ray. I can render it in mental ray with a displacement map.. but I cannot get it to reproduce the detail without crashing my computer (only 768 RAM). As I turn up the subdivisions in the subdiv approximations I can start to see the detail.. but can't get a render out of mental ray that is even halfway as detailed as the original z-brush render. If I crank up the alpha gain it just inflates my model...I'm pretty sure I'm hitting a memory limitation. But perhaps not... what I am doing is this: a.) create document in zbrush that is 2048x2048 b.) draw tool c.) switch tool to lowest resolution and switch to Morph Target d.) create displacement map e.) choose flip in V option and export alpha as a .psd doc f.) open in photoshop with colormanagement off and save as 16bit rgb tiff doc. g.) open maya.. run zatt6, which sets up the displacement approx and subdivision approximation nodes on my original model, which has the same geometry as the morph target in z-brush. h.) now my model does have a polysmooth on it with a setting of 1. this is to ensure that I have all 4 and 3 sided polys, and no 5 sided. i.) render...now I can see that the detail is coming through in the right spots..but just not enough definition in that detail and when I try to bring out that definition by increasing the min/max subivs Maya explodes This is an example out of mental ray with subdiv min-3 and max-7 and the same with the displacement approx min-3 and max 7 set to spatial.. and fine, length is 0.000. I have tried 0.01 but no effect. As you can see the detail is coming through.. but not enough of it
