ZBrush Usage Questions
#1

Hi again, I’m working on the eyes and created a scaled up outer sphere around the models left eye (right side in the image) then removed material to allow the inner sphere to show through. Then I made a copy of that outer cutaway sphere and mirrored it across the vertical central axis of the model which placed it accurately on the models right eye (left side in image). Now I need to somehow mirror what is now the outer sphere on the models right eye (left side of image) across the center vertical axis of the object while maintaining it’s current location. Can someone please suggest to me how I might do this?

Also, are there any books on ZBrush4 that you might recommwith eyes_01.jpg end?

Maybe it’s just me, but this makes absolutely no sense whatsoever. :confused:

Okay, I would be happy to know a different way to go about this.
If you look at both eyeballs you see that the opening of the lid is identical on each eye. I want to have the one on the left which is slightly lighter in color to be a mirror image of the other eye, not an exact duplicate.

Any thoughts appreciated

Thanks

That’s better!

  1. Delete the one on the left (lighter one)
  2. Select the one on the right then click ‘Duplicate’ button then select the duplicate.
  3. In the Deformation submenu, make sure only x is selected on the ‘Mirror’ button then click the 'Mirror button.

and that’s it! it will be the way you want it.

PS: You could do the same thing for the eyeball.

Ah! Yes of course. Thanks very much.

I am a wood carver and have attached an image of a recent piece.after polishing_01_scaled down.jpg

Your welcome wilt!

Wow! that wood carving is really nice. It looks like you used some sort of errosion method, like sand blasting maybe? I’m curious as to how you did it. Very beautiful work.

Thank you,

I do this with a CNC machine which means I am using some sort of CAD/CAM software and in this case it is ArtCamPro.

I have been getting into 3D printing though and want to learn ZBrush so I can print out my work as maquettes.

If you are interested you can see more at www.willtait.com

I am really enjoying/appreciating the interchange here in Central.

Regards,

I have tried the suggested procedure but ended up as before. After deleting the one on the left as specified, then selecting and duplicating the one on the right, making sure x axis is only one selected and click mirror the object is mirrored over to the left side but on a global axis not the axis local to the individual object and I end up with what I already had.

#9

? NOSE BLEED okay I don’t really understand you. you may want to try subtool master, and then do a mirror on their.

“I think we have a failure in communication” :lol:

Can you post an image and indicate on it, what it is that you are trying to achieve?

I think we could understand you, if you post more pics and details. what are you doing, did you just duplicate and move it to the other side.

#12

What you have showed me matches my experience. Perhaps the attched image will help.eyeballs_01A.jpg
I don’t want to mirror from one side of the head to the other, I want the mirroring to take place on a y axis local to the object.

I hope this makes more sense

You are getting the offset on the left because your eyeball (not the eyelid) isn’t mirrored correctly. The eyeball on the left is further away from center of the head than the eyeball on the right. Measure the distance and you will see what I mean. Delete the eyeball (not eyelid) on the left and repeat the proceedure that I mentioned above. If you did what I mentioned above concerning the eyelid, then the eyelid is mirrored correctly and doesn’t need to be mirrored again because that would make it an exact duplicate of the eyelid on the right. If you are going to be doing more sculpting using symmetry then it is important to maintain equality on both sides of center. When you Mirror an object, it doesn’t just move it over to the other side, but it also flips it, like I indicated with the cones. I think the error to begin with was with the eyeball and not the eyelid.

Yes, I know I spelled length wrong! :lol:

#14

I think you have hit on a crucial factor. Sculpting using symmetry. This problem would never exist if i could sculpt both eyelids at the same time using symmetry. And I thought I had worked out how to do that but then lost it.

So, let’s say I have two spheres, one in each eye socket. How do I get both of them to respond simulatneously to the brush?

Thanks for you effort by the way. I appreciate it.

#15

If the 2 spheres are seperate subtools, you will have to “Merge” them first.

Many thanks for your concerted efforty on my behalf. I really appreciate it. Hopefully as I learn ZBrush I will be able to contribute back to the community as you folks do.

can you still access the low poly of your eyelids?

#18

Slight progress in the desired direction.

Let’s see, what was the beatles once said?

I try, with a little help from my friends. :wink: Thanks again.

First, no I cannot access low poly on either the eyelids or the eyeballs.

Steps I took to get to the last posted image.
I was in level 6 sub div for the head when I created the appended eyeball and second (scaled up) sphere for the eyelid, so perhaps there is no lower sub div level for these objects. Maybe if I had been in the lowest sub div level of the head when I created them they would have started life at that lower level. This is something I will definitely want to check out.
I was unable to succesfully merge so I deleted all the old eyball/lid combos and started over by creating a single eyeball, copied and scaled it up for the eyelid then moved it over a bit since eyballs don’t live centered inside the lids. I then cut away the opening of the eylid using the alt key with the clay build up brush at a z setting of about 14, brush size about 24 with a lot of dropoff (I forget precisely how much) then using the same brush smoothed with Shift at about z 20 and brush size about 32, again lots of dropoff. Worked back and forth a bit then copied and mirrored on the x axis only to get the left side. I will be deleting the left side and doing more work on the lids but I wanted to post current level of progress showing both eyes and lids.

Hopefully others new to ZBrush like me can possibly benefit from this struggle. I’m feeling pretty good about my progress even though it’s going a bit slow.

Onward!

My appologies Will! I forgot to mention that merging subtools on higher subdivision levels will destroy lower subdivision levels, but also keep in mind that lowering the subdivision levels before merging will also destroy any detail that you had on the higher levels. If you intend to use symmetrical sculpting however, you can not do it across multiple subtools. A little forsight is neccessary in this regard. Just think of it as playing chess and try to see a few moves ahead. :slight_smile:
