Glad to hear it’s not just me! 
Hey everyone! Im having a problem with my Zbrush 3.2 and im in need of some help!
It seems that after working on my mesh for some time, the Ztool became corrupt and i cant export the mesh, import another, append to the ztool or use GoZ with it… The last working version of the model i have will take my work back 3 days so if anyone knows anyway to get around this ill really appreciate it!
Thanks in advance!
Okay, I’ve gotten the hang of modo 401 (so sweet), and now I’m onto combining it with ZBrush OSX 3.2 via GoZ. Not having much luck unfortunately. Might be a setting issue in modo to show the ZBrushed detail, as I’m still not incredibly familiar with it.
I followed the instructions on the video, and the meshes are bouncing back and forth fine. However, no hi frequency detail shows in modo. Hitting tab to switch to subd mode makes it nice and smooth like the original ztl, but none of the small stuff shows at all. Here’s what I get:
Any diagnosis? The ZB export scale is at 1 w/ xyz all at 0. The disp map is 2k. Are there any other non default settings in modo to adjust, or any steps not mentioned in the video?

I am doing the same thing - I am new to Modo and getting used to using GoZ, but I do not have that issue so I don’t think any steps are missing in the pixologic video instructions.
both modo and zbrush are so killer. also, though, you’re more experienced with 3d than me. (definitely a fan) i’m sure i’m the problem, i just don’t know what my problem is!
I fixed it!!!..by doing nothing! Last time I had modo and zbrush open initially. This time I closed everything, reopened zbrush only, did some detail and goz’d that bad boy. Instant awesomeness!
This means that I didn’t follow simple instructions. Happens all the time.
Man that renders the detail good! Whoa! It’s on. :evil:
I’m gearing up for a project I’ll be starting in October. Meanwhile, I still have more to learn to confidently use these new 3d tools in a project. So, I have a couple questions regarding GoZ and any insight is greatly appreciated.
1 - I I hit GoZ to modo and every thing works great. When I GoZ back from modo to do additional sculpting, I have been turning off the displacement map, sculpting the polys ZBrush style, and creating a new one for each GoZ transfer. Is that the correct workflow?
2 - I’m also new to uv mapping. I’ve been very easily applying puv tiles. Is this the best approach to uv mapping organic meshes for use with GoZ? (I know it’s the newest) I only use renders for art, so there will be no animation, etc.
Thanks in advance for any feedback. I’m sure I’ll have more questions, but so far I’m loving GoZ.
Told you I’d have more questions!
In modo, the 2k puvs displayed and rendered fine on the demo head with random detail sculpted. I jumped back to ZBrush, deleted the UVs, made new 4k puvs, hit GoZ, and in the modo display I get this crazy guy! Kinda cool! Oddly enough, it renders great! But what is it a symptom of?

Oh I am in the twilight zone!
This is a close up of the demo head’s chin. Take a close look. Separately, I am working on the 2010 Kentucky Derby Festival poster. Check out the backwards Kentucky on the chin which is font from the poster!!!
I actually would love to get a render like this, but they come out fine! :lol:
Time to look in the GoZ folders.!
*Update - I searched every folder that I know to be related to GoZ, but surely I missed something. I found no files from the derby poster! This also happens with the dog ztl. All disp maps look fine in photoshop.
AGAIN, the 2k puv with disp map doesn’t show this craziness, so that might be the issue?? This same thing happens with all uvtile types.
Ok, I’m officially lost!
James try hitting tab. Does that fix it?
Nope! That is how to get the smooth render though. Gotta love the modo subd mode 
With the festival poster image appearing in these artifacts, I’m sure there’s a file somewhere in the crossfire. I just can’t find it!
I have identified that the display artifacts are connected to the displacement maps though. Only thing is, they look fine in Photoshop.

It may actually be a 4K issue. I will have to look into it but maybe Modo has an issue displaying 4K maps. Just a thought. I would look at the luxology forum for that info.

I actually just did a project based tutorial in modo using 4k maps, so in general they work fine. However, it could be an issue displaying the 4k tiles.
I really think I’ve misplaced a file because my poster art, which is 2d w/Photoshop, is actually displaying in these artifacts, but backwards and scattered. So weird. I agree that it’s just as likely to be on the modo end, so I’ll post on their forums and see what I find. I’ll also continue my search for that misplaced file.
The beauty of this “issue” is that it hasn’t seemed to affect the renders! (so far) With ZBrush and modo I’m producing some sharp final renders with GoZ. It’s a much more powerful work flow than my old compositing method.
Anybody have any luck getting GoZ to work with C4D R11.5? I can get C4D to send a cage to ZBrush, but ZB can’t seem to find C4D. I hid my older version of C4D, because it was going there. How do I redirect it?
thanks, eric
FOR MODO GOZ USERS:
I’ve solved the issue, and boy is it strange. It is in fact a modo bug that occurs with some video cards when displaying 4k maps. I haven’t tried higher. It’s related to the OpenGL texture display resolution in the modo preferences. If you end up with similar issues that I had above, do the following:
-Set the texture display to 2k in the modo preferences opengl setting
-Close modo
-Delete the UVs and Displacement in ZBrush
-Assign new ones
-GoZ to modo
-Let out a sigh of relief
Photoshop CS4, where I’m doing my 2d art, uses opengl as well. An image of the art must be stored in an opengl clipboard or something, causing it to show in modo’s opengl error when displaying 4k displacement maps. That must be how my 2d art ended up displaying as a chopped up displacement map on my 3d GoZ model! Really, I still have no clue, but it fixed it.
A cool dude from Luxology forums helped me out, and everyone who has experienced it ends up with random textures that have nothing to do with the current file!
WEIRD. However, all is well now. GoZ!

you can use the redirect application found on the first page of this Thread. You will find a the selectGoZapps_modo.zip. Use that to see your Modo application.
Paul
Glad to have it back.
Thanks, Paul!
I just noticed that it’s full of files… Does that mean that GoZ creates a back-up each time you go from ZBrush to (in my case) Modo ? Are those cache files only ? Do you still have to save the tool in ZBrush ?
Hi Guys,
I’ve recently started using Zbrush and I can say that I am really impressed by the results I get from it. Unfortunatley I stumbled against a frustrating problem:
I just modelled some lips on a surface and I want to combine them with another body I modelled in Solid Works (This part has been exported as a OBJ)
Now I managed to put both parts on the same window, by using the subtool feature. Now my problem is the follows: The part I exported as an obj, is significcantly bigger than it should be and I need to scale it down, but ZBrush won’t let me. Is there a way of scaling parts down when they are in the subtool feature?
Any suggestions?
thank you
