ZBrush andTruespace ZB crashes

[MikeHart]

Hi all,

I purchased ZB last night. It's really an awesome prog. The main thing what I wanna use it for is exporting models from Truespace and texture them in ZBrush via TextureMAster. My problem is that everytime I wanna export it as a OBJ_File vom ZBrush, it crashes. Does anyone know why and if there is a way to do this? I export from Truespace as a DXF-File.

That's weird , I've exported in obj format a couple of times and I didnt have a problem , blame microsoft :p

[Northstarr]

Yeh, I have exported in obj to both poser & bryce without a problem. But if I draw off the canvas I crash! I have to be really careful, I have lost some good work doing that! But it is probably not ZBrush, it is more likely Windows ME!! :rolleyes:

You could try exporting from truespace as an .obj file using this free plug-in. Might be easier keeping the one format throughout. Hope it helps.

You guys crack me up blaming an OS for an app shutting down. :p :td:

Gimme a break.

Blue screen, okay.

ZBrush bombs........not necessarily.

Although Win ME sucks. I'll give ya that.

oh well, I like my ME. Was just wondering since windows (whatever version) is a memory hog, maybe that is a problem.. Can't wait to get more memory! Gimme more MEMORY!! ok, am back to partial saneness.. really I have found if I work for awhile, that I'm really really slow and sometimes, I just run out, then ZBrush says, I revolt and shuts down. BTW, I only have 256k but am waiting til next payday to double that at least.. :)

I ran into the same problem bringing in a DXF from Poser. Most of the way through exporting as an OBJ, it goes bomb. Since DXF doesn't support UV mapping, I just hadn't ever dealt with that format before!

Anyway, I've brought this to Ofer's attention. Hopefully we'll hear something back before long -- I know that he's hip deep in programming and other preparations for MacWorld (which starts at the end of the week!).

I'll share whatever I find out here.

If, as some have stated, "it's the operating system causing crashes", why out of all the very many 3D & 2D graphics software packages I have installed on my system, ( Windows98 SE ), is ZBrush 1.23b the only one to crash continually??? :rolleyes: Mark.

I used to have Windows 98 and it was dog slow when compared to Win 2000 (which still ain't the best ;) But it can't be you're OS, cos there are people out there who have no problems with zbrush on it. Perhaps it's your set up or memory or processor etc?

[Muvlo]

I've had trouble with OBJ export from ZBrush a well. About other ZBrush crashes though, it is very rare for me. As Kruzr says, on Win98, ZBrush crashes continually. I had this problem too. But now I'm on Win2K, and ZBrush and all other programs are much better behaved. Win2K or XP are highly valuable upgrades. :)

I don't have a real key about it...

But if your model has lots of polygons, who knows? it often creates crashes while trying to perfom operations with huge models. If so, try it with a very few polygons model(to spot the problem).Export a low count sphere from truespace, and -without smoothing/subdividing- export later that one as obj. That will remove you the doubt if it is for polygon count (and so, memory-resources-computer_Power, matter)

Also, you could try converting that dxf inside a converter into obj and import as obj, but I doubt this is it; I used to import dxf and export the objs with zero problems.

It has been mentioned it could be related with the fact dxf doesn't have UV support. For checking that, try apply UVs inside Zbrush, and exporting as obj, and try it also without doing it. If you happen to see that while doing it in a different way than you did previous to post here, and it works, then it'd be that thing of exporting and uv coords. You will have spot it.

But I am more of the idea it maybe that the model is too big for your memory (or for the actual state of your ram, virtual memory(check both the SO and Zbrush values for virtual memory) , and windows registry and w98 config are non well configured)...or other SO related issues...like the file is write protected, there's not enough hard disk space (the virtual memory maybe is cosuming too much hard drive space in the operations with a big polygon count object)

In other softwares, strange hangs are produced when an object has some bad artifacts (double faces, inverted faces, etc) and the software can't handle them while in export.

I agree with you cannot blame the SO if you don't know really what is happening. It could be many things, really..and the best is to get to know if there's some bad operation being made in the proccess.

Anyway, NT, win2k, and XP are more stable than w98se and ME. I may be wrong but I think XP has got a better memory/resources handling than all of the previous ones.

I run WIN98SE, P3 500MHZ with 256MB RAM.
Should be enough. The mdoel I exported from Truespace was around 300 polys, a simple spaceship. I wrote to Matthew (technical support) and he recognized that prob too. He will forward it to the developers so maybe they can squish that bug and it will be out in the 1.5 version.
