Questions and Troubleshooting for ZBrush OSX 3.2, GoZ

[fidget]

Hello,

I am having 2 small problems with zBrush.

The first just started happening the other night for the first time

1. when I use GoZbrush to bring my mesh into Maya everything is fine, but when I render preview the scene my mesh from zBrush is not visible. Other objects in my scene that were created in maya are visible but the goZ mesh is not.

The only semi workaround I have found is to export the mesh as an obj from Maya or Zbrush then reimport it into Maya.

2)But this workaround leads to my second problem. When I do reimport the mesh into Maya and add the displacement map to the mesh, my mesh breaks apart in the render. (see attached picture) but if I reimport that same obj into zBrush and apply the displacement map it looks fine.

Any info is appreciated.

Hi there,

I work on a MacBook with system OSX 10.5.8

While sculpting, sometimes SUDDENLY the whole tool disappears and is not to get back.

I tried to solve this problem normally by saving the actual tool, quitting and starting ZB new.

When I load the tool again, it works again.

Until this morning: my tool dissapeared in a nirwana and has never been seen.

The finder shows 148 kb data, but all polygons are gone (I attach the file, maybe somebody can repair it?)(No stress, it was only a try-out-file)

Does anybody know this phenomenon?

Greetings,

Stephan

Hello,
I will be sculpting and once in a while my ztool will disappear, it is a bug where the mesh jumps away. This is how I fix it:

When your ztool disappears, get out of edit mode immediately by hitting T, then control N to clear the canvas (or command N). Now, draw the tool on your canvas again, hit T to enter edit mode, hit UNDO once or twice, then hit F to frame. You won’t see your ztool when you draw it on the canvas sometimes, but when you hit T to edit it, then F to frame it will jump back into view.

Hello,

1. You can make a macro that loops. This way when you hit the macro button your entire subtool list will be cycled through, setting the export numbers correctly on all of them in a split second.

If the scale values were constant, that’d work, but I thought part of the problem was that ZB’s GoZ script changes the scale value used for export, but only changes the values for the top-most tool – meaning you have to propagate the scale values from the top tool to all the other sub-tools by hand each time.

Am I misunderstanding the scale issue?

I dunno if this has been asked before, but if it is, then please point me to the right direction, I would really appreciate it.

My problem is, I just installed maya 2008 and zbrush 3.2 in mac osx snow leopard. Maya 2008 is working fine and so is zbrush, and I followed the video tutorial for using GoZ for maya, but whenever I click the GoZ button, all the choices are grayed out. I can’t select one. I’ve tried restarting the system, but still I got the same problem. What seems to be the problem here?

Hello

have you tried the Application selector that you can download here:

http://www.zbrushcentral.com/showthread.php?t=72585

Give that a try to see if you are even seeing Maya on the system. If that does not work then I would create a ticket on support.pixologic.com

Make sure that your Scale and Offset do not say nan on the tool you are GoZing over. If they do then you will need the original scale and offset of the tool. Do you have the original version. If so then check that tools scale and offset in the Export Sub-palette to get the number to be put on the newest version.

[fidget]

Thanks Paul. The scale and offset where? Under which tool?

I started the sculpt over as a practice to see if it was the sculpt and I got it to go over with out breaking apart, I think there was not enough polys in the head.

But now I always get this weird stuff happening to my piece in Maya.
As you can see in the picture below, those black squares should not be there. Why is this?

Do I need to use the retopolgy tools to bring stuff properly into Maya?
I am not doing animation, just 2D renders.

Do I need better UV’s on my model?
I am making them out of zSpheres and use the AUV tiles (PUV always “cracks” the mesh)

I was trying to make a holiday card but it looks like zBrush and Maya are conspiring to not let that happen.
I am getting pretty frustrated.
Can I pay someone at Pixologic who knows this stuff for maybe an hour of phone time? I need some questions answered.
Any help is appreciated.

aloha,

Hello Fidget

Are you rendering a Normal Map here too? Private message me to work something out. We can speak on the phone or just send me the tool so I can take a look at it.

Paul

[system]

Try to merge verticies and smooth normals inside of maya. I find I have to do this because the models do not come into Maya with UV’s together.

[fidget]

thanks for your answers.

No, I did not render a normal map. should I be doing both? I thought it was either or.

Paul, I am sending you a PM with a link to download the file. I am leaving for the mainland for 2 weeks and will not have Z with me, but maybe when I get back we can chat if help is still needed.

Mahalo,

Wow, really kind of disappointed that it seems we’re going into the Christmas break without a new Mac release. I’d love to be pleasantly surprised, though.

TheSnap: I am also having that sometimes. Very annoying.

Also, about crashing/freezing: That has happened with all sorts of polygon count, from a million to 6-7 million. So, no i don’t think it’s a memory thing or at least not entirely. I’m just hoping (and really thinking) these are unfixed bugs in the program which should be (and are probably) taken under consideration for ZBrush 4 or for mac versions.

I would like to update to Snow Leopard during these christmas holidays, I am planning in installing Snow Leopard from scratch. (format the disk, then install SL and re-import everything from Time Machine).

I have two questions:

1. Do I have to do anything like disabling my license or anything before installing it again?

2. I still find the “camera” behaviour annoying on 3.2 compared to earlier versions of ZBrush, is there any way to make it work the other way around? I mean that it rotates around the last point pressed and I have to be pressing local transforms over and over again to enable/disable…you know…

(I know that there is no camera, that ZBrush actually rotates the ztool or scales it instead of orbiting around or zooming in, but you know what I mean…right?)

Tip of the day for modo users. Put multiple items in a group locator. Select the group and it’s contents in the shader tree. GoZ. Polygroups>Auto Group. Subtool>Group Split. Bam. Subtools.

If an item has multiple individual meshes, it will split those into separate subtools. This is good if they are touching. Not always what you want,but for the most part, .

Hey. I have yet another problem that’s killing me…

Working on Mac 10.5/ZBrush 3.2

Too many times now, i am getting ‘‘error reading file’’ in Maya when i use GoZ in ZBrush resulting in that i get my model in Maya, but no material, (only wireframe) and no maps applied to my model.

Does anybody else have this, can tell me why it happens and has been able to solve it?

Thanks.

[TheSnap]

Hi Hunter,

all the change-files which are exported you can find in User>for All Users>Pixologic>GoZProjects>Default
They are all collected there. I think it is useful to delete sometimes those files.

Wish you all a Merry Christmas!

Here’s a newbie question for ZB. I’m using OSX 10.5.8. Maya 2009, ZB 3.2 with GoZ.

Generally, I’ve been able to go between Maya and ZB by using GoZ without too much trouble, as long as I save the tools with the default GoZ names. If I rename a tool with a name of my own choosing, I get an “Error reading file” message in Maya. Why is this happening? Is there any way around it? I don’t think I saw anything about this in the docments and training vids.

Thanks,

it looked like several people in this thread were getting the blown up displacement problem in modo. i think maybe a few people here know how to fix this?

i posted my image in the link below to my problem. since i saw others with this too. if anyone has any idea could you please give me some info? this is…frustrating…

I had a similar problem using GoZ and Modo, all I had to do was hit ‘tab’ and all my seams were fixed. But, it may not be the same issue.
