ZBrush Usage Questions

Aurick, I’m the one who had the problem with the above video tutorial that is in Italian. I thought I had figured it out, but I only have part of it figured out.

If you could be so kind to look at exactly the 3:50 second mark of the above video, you will see that he has merged the layers, and saved the image…
He then re-enters Zbrush, and accepts all edits…

The head is turned in a side view, or profile view. His Model, along with My model look perfect at this point.

When he goes to “Pickup” from Projection Master, I do the same thing, and THAT is where my problems start. Everything matches up tutorial wise until this point @ projection master pickup.

I feel it necessary to emphasize this point: After I save in photoshop, and re-enter z-brush, it’s beautiful. Just like I want it. Matches up perfectly with the tutorial. It’s only after I hit “pickup” in projection master that my project goes bad. The 3d head shows up, but the texture part does not. It just shows up only as a light brown color, vaguely resembleing the skin color of the photoshop work.

Another note: In his video, when he hits pickup , on the left side of z-brush, (above the shader button) His texture icon changes from a solid white to a white with the skin texture inside of it.
When I hit pickup, my texture icon remains a solid white. It does not change like in his video. Any ideas? I must be missing a single step somewhere. Everything else is perfect.

Sounds like you don’t have any UVmapping on the model (?)

I’m not a Z-expert though. But you might want to try applying some UVs to the model and trying it again.

Best regards

thank you very much for the reply. Yes, it has to be something very simple (usually is) that is the sore spot. I know I’m a noob, but I am extremely detail oriented. My job 10 hrs a day is to pay attention to detail. That’s why this is driving me nuts. I’ve narrowed it down to few things though.

It has to be:

  1. a setting I am missing somewhere in the tutorial. Because it’s in Italian, and I don’t speak Italian, I’m already handicapped. Sight only.

  2. My .obj is not compatible …so to speak…because it was made using Facegen. (3d facial program…u feed it some pictures of people, it spits out a .obj

I have done some searches on here for “facegen”, and I may have come up with something. It seems there is is problem just dropping in a fresh from Facegen .obj. (at least along the lines of what I am trying to do)

:qu:

Well, while you wait for one of the thousands of pro’s to give the correct answer and the “doh!,… I knew it was simple!” solution, try a quick test on a new model.

Import the obj. Apply UVs to it in Z. Go through the normal routine for zapplink and Z.

Should only take a couple of minutes to give it a whirl and see if you have results.

That series of tutorials was very well done. (regardless of the fact that the only word I know in italian is ‘dressing’.)

Best regards

I guess I could’a just said to run a UV check on the model in Z. (Texture>UV Check) If it (the model) turns red then you have no UVs or overlapping UVs and they need to be applied or corrected.

(hope I’m not steering you wrong… hate to waste others time)

Good luck

Sorry, didn’t mean to imply I wasn’t going to check into what you were saying, just that I had a hot lead in another direction …ie my .obj could be messed up for Zbrush.

OK,I’m all ears…Opened my .obj, did uv check, all red.
I blush to ask, but what’s my next move? How do I go about applying uv’s? And how many do I need? Thank you sir.

Well,… you can just use the built in automatic UVmapping supplied with Zbrush. You can simply click the AUV or GUV button in the Texture pallet. Problem with these types of mapping means that you can’t really do any outside editing of the mapping once you are done painting (IE… touching up in photoshop is simply not possible, as the map consists of squares that represent the polygons, and they are not sorted into a viewer logical order) <— yeah… lots of words… whadda ya do…

There are freeware programs out there to do you own UVing with. Google the answer or perhaps someone might chime in with their best suggestion(s) I think there’s something called uh,… UV Mapper or UV mapper Pro that is free.

Or you can do your UV layout inside your main 3d application, assuming you have one. You can do your own HELP search in your 3d app for instructions.

Hopefully someone will help bail me out with some better guidance here before I get you too frustrated.

Best step at this point, until you get a UVmapping program would be (mind you I’m not a Z-pro so this is my best guesses);
Import your obj model-- go into edit mode (T)
Click on texture pallet
Click AUV Tiles
Click on texture in main bar top of screen and create a “new” texture. (be sure to set it to an ample size 1024 x 1024 and make sure you have the color pallet set to white before you click the “new” button)
Make sure your model geometry is divided enough.
Go to Projection master and drop the model
Go to Zapplink and let the painting begin. Follow the Italian tutorial from there and you should be fine.

(Hopefully someone else will chime in if I messed up any instructions… or they can guide you with help in the UV department. In other words,… please take over any time Aurick, you know you always have the best answers and we all are very appreciative of your help and sharing on these boards !!)

Best Regards

Never mind. Answer to my specific problem found. Facegen Imported .obj, following the tutorial in italian. I don’t know what it means. All I know is that it works now. When I pick up from projection master, it looks like it should, (at this stage) Pic included.

By the way, if you’re using ZAppLink there is no need to use Projection Master. ZAppLink has its own ability to drop and pick up a model, using routines that have been optimized for use with ZAppLink.

If you’re using ZAppLink you will get the best results by NOT using Projection Master.
