deleting hidden mesh makes you lose lot of the high frequency detailsl. reconstructing subd doest help. this bug still hasnt been fixed?
this is an old bug but it still seems to be here in zb3, along with many other bugs.
i am just wondering what happened will all the beta testing, was it just making promotional images or actual bug fixing?
Reactor -
I figured out the WIKI thing (did the new FAQ page)… so that would likely be the best place to shift this info, as it’ll allow anyone to update and hopefully keep things fresh/sorted.
Still happy to help in that regard, but I think Pixologic will have to make a page/place for it in the wiki first…
I looked through the first post and I dont think its in there, but I keep getting this annoying bug that happens when I right click to bring up the sliders to change my brush size or z intensity. If Im holding a certain combination of buttons (ctrl / alt / shift) while doing this, sometimes my model & all of ZBrush locks up and I cant do anything at that point but right click & close ZBrush from the taskbar.
Im trying to figure out what key combination I can use to intentionally cause this, but it seems to occur somewhat randomly. Anybody else having this problem?
Thanks zerodean! I’ll look into it today, and if need be, put the request into Pix for some wiki space. I’m in total agreement the wiki is the next best step for this…
Yes, I’ve been having this problem since the old Z2, and apparently, it still exists in Z3. The lockup seems to be only on some functions. You can still save the doc via ctrl+s. My solution is to bind psnap to a hotkey and autosave when this occurs. I posted this issue several times before but fall on deaf ears. I think it’s because it’s hard to reproduce. And I can’t seem to reproduce it at will, but it still happens from time to time.
I have a mesh with layers. I wanted to local subdivide an area so i went back down to subdivision level 1 and locally subdivided. Now my layer subpalette is disabled. :evil:

try setting a morph target at your highest level before you delete anything. and switching to it after you’ve deleted whatever. in most cases i’ve found it’s a workaround / fix for that same problem you’re having
I just noticed the same thing…very frustrating 
I think ALL beta tester deserve respect!! They are professional.

I think I posted this in here somewhere, but, I can’t remember and I can’t find it.
Anyway, unpinch don’t work in Z3.
In Z2, if you pinch vs unpinch (that is pinch with alt pressed):

feureau, the pinchvalue is just a offset
im not sure but i think if you use the pinchtool with a 0 value you can pinch and unpinch
instead of unpinching you could just use the smooth brush :>
another problem: the mat cap arrow keep snaping to extreem angles and wont let me choose different angle…makes it a nightmare to get the right shade for the right angle…
Well, the value is just an offset like in flatten etc. And alt-pinch at zero is still pinching at zero offset.

Thanks for the reply, anyway! 
When you say extreme angles, did you mean it snaps to the axis? Maybe you got your shift locked. There’s a shift alt lock on zb: press shift, hold it, press alt, hold it, release shift, release alt, it’ll lock the shift. Same with ctrl-alt. If your mc snaps, try pressing the alt to release the shift-alt lock.
Good luck.
Thank you Reactor for creating this post! It is very organized and up to date! This is made in the same style that I would do it in. Nice job!
No worries Gargantula… it could be more up to date! 
I’m still trying to get in contact with Pix about a wiki transition. Hopefully it’ll be soon…
Um… you don’t need them to do anything to create a wiki page at the wiki…
I mean, you can request that they link to whatever page you create from the main wiki page, but otherwise, anyone can create any new page at the wiki…
example:
http://www.zbrush.info/docs/index.php/ZBrush_3_Workflow_Issues
A link from the main page was pretty much what I was hoping for…
Great thread.
I’d like to add these findings. I haven’t seen them in the first page and I hope I’m not repeating them:
When reimporting an OBJ (with UV’s done externally, for example) into an existing tool, if the importing flippings (xyz) settings aren’t the same as they were when the original mesh was imported/exported, Zbrush crashes.
When reimporting an OBJ (with UV’s done externally, for example) into an existing tool consisting of the same mesh devided into subtools, Zbrush either crashes, or simply adds the entire imported mesh into the selected subtool.
Thanks for managing this topic, Reactor.
UVs wen brought into zbrush (2.0 or 3.0) or exported back to native 3d app. either way is a nightmare for me. we are a gaming studio working on xbox360/pc titles and Unwrap is a very much keystone importance in gaming studios. no improvement in zb3. its rather getting worst.
dang, I was hoping you can embed youtube vid in these threads.
A while ago someone posted about ZSlowdowns, I think I finally figured out what happened. When ZB tools is zoomed way out of the borders, it will somehow slowdown Z3. Even with the faux shadow off, it seems to still exhibit the slowdowns.

Although, I suppose it’s normal behavior, since ZB is calculating more pixol occupying the screeen.
