Why can't I edit my object anymore?

ZBrush Usage Questions
#41

I’m a newbie and have just played around with the ZBrush demo version for a few days. There are a lot of new concepts but it is fun.

Anyway, as this thread describes, the internal transformation of an object from “edit” mode (3D) to “draw” mode (2.5D) happens as an optimization and is necessary for oll of the fun stuff to perform at all. As a professional software developer, this makes good sense to me. It also makes sense to me that some information is lost, e.g. any information about the “dark side of the moon”.

So am I right in assuming that ZBrush is not really a 3D modelling tool but more of a 3D post-processing tool with some inherent capabilities beyond what a 2D program could offer?

But, oh boy, would I have liked to be able to convert freely from 2.5D to 3D. I suppose this is due to the information lost in the 3D->2.5D conversion? I’d suppose one could retain more 3D info by letting each pixol link to a linked list of hidden pixols facing (alternately) backward and forward. Still, there would be the problem of rounding errors in the conversions, especially for surfaces perpendicular to the clipping plane.

Well, I suppose one day it will be possible to model with this ease in 3D …

PLZ help
I had this problem too, and then when I tried to save the tool, the “save as” button in the demo version was unavailable…
Is there a way to do this?
:cry:

Not with the demo. The demo can only save the canvas, which means a snapshot of your model rather than the actual geometry. This is part of the incentive to purchase the commercial version – so you can continue your modeling adventures across multiple sessions.

Ok, I understand how to mark an object, but when I wanna edit-it again it’s not the model I have marked before, is a copy, and now I have (in this case two faces on my scene, the original, and a copy when I tryit to re-edit)

Another question I can’t understand at all is what can I do to put the eyes on the face.

#45

check out the newbie challenges in the challenges forum…there are two that deal with eyes.

#46

So wait, does that mean you have to decide how your picture is going to look almost as soon as you begin? Like where it’s going to be on the stage and what angle you look at it and everything…

Painters have been doing this for thousands of years…

Fine…

now these days it’s called using your imagination

I’m pretty sure it’s always been called using your imagination.

Thanks for this thread. I am checking out the demo version and re-opening an object for refinement was not obvious to me either.
I downloaded the sea creature zsphere object from this thread:
http://www.zbrushcentral.com/zbc/showthread.php?t=6769

I imported it thru the tool palette and have restored to an editable state, but when I preview it, I don’t see anything…

Any help will be appreciated.
Thanks.

hello i recently have discovered zbrush2. im fine designing models an stuff. but i have noticed soon as i enter projection master an want to add an alpha to paint on the model i have realised it stays at the same direction so all my move,scale tools are disabled. yet i was watching an aaron sims tut an he was able to drag these alpha 360 degree`s after choosing…

not quite sure if i need a plugin or something for that to work but would be nice if someone could tell me how its done. thanks

#53

You don`t need any additional plugin.
All you need is to choose the directional brush in projection master instead of simple brush, then you can scale, move and rotate the alpha.

#54

I dont get the Reselect to work, can someone tell me this step by step plz?

#55

if im saying this correctly. when you start modelling you get a step by step view of your model inside the tool section so if you mess something up or decide to change it to unified or adaptive skinning create a polymesh it becomes available inside the tools palette you just select it then redraw back on the screen then click EDIT to continue modelling, Also its exactly the same as when you save your work say you close zbrush an reopen you are shown the empty document load up your .ztl of your zsphere`s or whatever you made an you need to redraw the model back on screen with the tool you saved to re-model…

im still pretty new to zbrush but have watched loads of tutorials so i hope ive helped you there.

also want to add to this… when in zsphere mode still an you open the tool you saved as zspheres you can still toggle the preview mesh with A an add more zspheres to your model.

Okay so I started my first model in zbrush and I got to a point that I want to save so I didn’t lose anything only I saved it as a document.

So now I open the document and the model is there in pixols but when I try all the tricks to convert it back nothing works. Can someone help me? I have no idea what I’m doing and I’m kind of dumb tonight so please explain it as simple as possible lol…

Edit: I uploaded the file if that helps to show where I’m going wrong. Sorry about it being a zip of a rar file I was having trouble with the size requirements when it was just a zip file.

Rebourne, have you saved your model as tool or you have saved the document??? I have saved my models so many times, but as tool, and every time when I continue working, everything is there where I have stopped.

#60

Rebourne, I have just tryed to open your alien head… I think you will have to start all over again, you see, the only way to save your models is to save them as tools, and when starting again on new document, load that saved tool…

maybe there is some way in ZB3 to convert your pixel model in to OBJ, but I do not know it
