Need Help Understanding Zbrush to Maya Workflow

ZBrush Usage Questions
#1

I’m on an 8-core intel Mac, 8 gigs RAM, zBrush 3.2 clean install. Using Maya 2008.

I’m having some issues with getting my displacement (and sometimes texture) maps to display correctly in Maya. I have been using Maya since 3.0, but am pretty new to Zbrush. This is my first model (other than tuts) that I have built from scratch (zspheres) in zBrush, and am attempting to use the new GoZ function to bring it into Maya for rigging and animation.

I have attached renders from both zbrush and Maya so that you can see the differences. The main issue for me is the wings, the back edge is bloated, there are several ugly seams, and a significant loss of detail.

You can see the settings I used to create the UVs and maps in the Zb screen (I used GUVtiles), but I have tried several different settings, and this is as close as I was able to get it.

Can anyone help me understand what I’m doing wrong? I feel like I probably made some workflow mistakes while building this character, but I need some help understanding exactly what I did to avoid it happening in the future, and plodding through random searched threads to figure it out myself isn’t really helping me.

Any insight would be greatly appreciated. Thank you.

Use Auto instead of DPSubPix, which allows you to use a consistent alpha gain in Maya of 2.2 on your displacement map.

To get the most detail from your displacement map in Maya, make it at least a 2k map. Remember though, that displacement mapping isn’t good for tiny details like pores. It’s good for stuff like shape and form. Small details are more easily achieved with a bump map.

Thanks for the response.

To use auto, do I simply set the DPSUbPix to 0? I tried that, and it looks the same in Maya, is there another step I’m missing?

Im having exactly the same problem… Seams in maya…

Please someone tell me how to fix this…

I have good uvs that i layed out, and 4k disp, normal and colour map. All passed to maya through GoZ.

Thread bump!

Ok so why does GoZ rip apart UV seams?

That seams to be the issue (No pun intended)

Is there a rational reason for this?

The seams look stitched but you can move them.
