Transfer Pose

ZBrush Artworks
#1

Hi

Let’s say I have 2 heads on 2 different Zbrush file.
They are excatly the same, except that one is posed, and the other one no.
Is it possible to make modifications on the unposed head (neutral one) and then transfer the pose from the posed head, on the new modificated one?

To sum up, can we transfer a pose from one model to the unposed same model?

thanks

If the topology of the mesh is the same then yes, you can do it:

  1. Export the lowest subdivision level of the posed model. Press Tool>Export and choose “GoZ Complete Binary” from the file type dropdown.
  2. Select the unposed model, go to the lowest subdivision level and then import the GoZ file you exported at (1).

Thanks for the reply.
I will give it a try and let you know.

meanwhile I found something that seems to work, but the 2 meshes MUST be exactly the same (topology wise and so on).
Usually, I save a file when my sculpt is final and unposed.
Then I do another file for the posed version. And it’s better to have this pose version on a layer.
Basically these steps can save you when you forgot to pose your model on a layer, just like me.
Here are the steps and I just tested on a small piece, it seems to work:

A-For the neutral mesh in HD
1-Lower subd level to 1 and delete higher
2-Export as .obj

B-For the posed mesh in HD
1-Create a new layer and name it “Pose Layer”
2-Set subd level to level 1
3-Import the obj of step A

Now you have a “Pose Layer” to play with.
When it’s on “0” it is posed. When it’s on “1” it’s neutral.

C-Modifications
1-Create a new layer and name it “Sculpt Layer”
2- Set layer “Pose” to “1” so it’s neutral
3- Sculpt on the “Sculpt layer” to make the changes
4- When it’s done, set layer “Pose” on “0” to see your HD model posed and with your changes you just made.

Do you have full control on the subdivision level ?

Yes, provided the topology is the same, your subdivision levels should be intact. I suggest using the GoZ format because being a binary format (unlike OBJ) it’s more efficient, and it also will keep any polypaint, creases etc.

With your method (A), not sure why you’re deleting higher subdivision levels. That’s not necessary.

I edited my previous post before I saw your answer.
thanks

this is the issue I have using your method :

Ok so I tested your method

I want to modify the sculpt in neutral pose and then apply the pose from posed model on this new neutral model without losing the new changes.
With your method, it does apply the pose on the neutral mesh but changes are lost as well.

any idea?

It sounds as though the modifications you’ve made are altering the mesh at the lowest subdivision level so that your posed mesh and unposed mesh are too different. Every change you make to the higher subdivision levels will affect the lower levels to some extent, so really you should only create fine detail at the highest level using your workflow.

A better way of working would be:

  1. Create your model in a default pose.
  2. Create all the detail at higher levels.
  3. Go to the lowest level and pose. (Or copy lowest level to pose as a separate mesh if you wish.)

Yep thanks

I just tested a mix between your method and mine.
Instead of exporting/importing in .obj I use your GoZ complete binary suggestion.
And playing with layers, it seems to work.
I will just repeat the process for the few pieces that I need to change and it will do the job I guess.

Thanks for your help and advices.
