ZBrush Usage Questions
#1

trivia question of the day: who can tell me what is wrong with these .zpr and .ma files?

my computer is already having graphics card issues (rosetta trying to run graphics-heavy 32-bit applications on a 64-bit machine), so this might be a problem with the graphics card. but these problems feel different than the normal graphics card problems that i have, especially since these are more consistent.

problems

zbrush:

***8226; subtools based off of spheres won't UV map correctly***8211;***8211;they produce two UV maps for each object, which then cannot be used to transfer texture and normal maps***8211;***8211;and won't allow import of maya maps (says that the files cannot be found or read)

***8226; base female mesh won't create texture map from polypaint; will do hands, but everything else is black

tool > texture map > new from polypaint: hands map successfully, though it changes some of the visible texture for some reason, but the rest of the model turns black

maya–using GoZ from zbrush
***8226; all objects have weird smooth effect on the edges of the models; the normal map texture does not extend to the edge of the modela friend said that he has this problem going from zbrush to maya when his UVs overlap; mine are not overlapping on any of the subtools and all UV maps are separate from each other

this is happening on all of the models, but i just showed the aprons trap since it showed two edges close; also note that the smoothing does not cover a whole polygon face

what the edges of the strap look like when GoZ’ed into maya; note the normal map does not stretch to the edges of the model, unlike the color texture map, both of which use the same UVs

all right, a school colleague of mine said that some of this is happening because some of my ztools are named weird. but i don’t know what he means, and i don’t know how to fix it. so i’m including a sreenshot of my ztool list. can anyone tell me how i am supposed to fix this?

the ones that have custom labels seem to be screwing up, but if i don’t have custom labels, i can’t keep track of them.

ok, i have fixed problems #1 & 2, but #3, the weird smoothing on the GoZ’ed models is still there, and i don’t know how to fix that.
