Dynamesh without touching selected subdivided high poly mesh


#1

Hello there,

This is my last zbrush work, this model has a 25 million polygons (6 SDiv)
The problem is that I forgot to sculpt ears…
How can I sculpt them back with dynamesh, but without touching my high poly mesh?
Is there a way to mask all details and dynamesh a selected part? Later I’d like to zremesher one more time and get back my details.
Is this even possible?

This model was made in process:

  • dynamesh
  • zremesher
  • reproject
  • high poly details

Thank you for your time!

What does your lowest level look like? 25 million polys is a really heavy model (looking at the detail in your model I would say excessively heavy) but should also mean that you have enough polys to sculpt in the ears without causing too much trouble.

Failing that you could duplicate the tool, dynamesh it with a relatively high level to preserve as much detail as it can, add the ear, zremesh it then subdivide and reproject the original.

Does that make sense?

To me? It makes it. But im wondering if there is still another way to make it.
Thanks!

tone it down instead of 6 SDiv put it to 5 SDiv or maybe 4
then make it a polymesh 3d , this will kill the subd level because in the next step you dont want subd levels.
1 mask where you want the ear
2 tool>polygroup>group from mask
3 brush>imm bparts once the brush is active press M key and then select the ear body part
4 mesh fusion the ear https://www.youtube.com/watch?v=Y7VQUZOhMDM
5 shape the ear like you want it like push and pull and maybe smooth the edges
6 divide the mesh, if you get a error its to high then on the top step tone it to SDiv 4 and start over step 1 threw 6
7 if no error tool>gemoerty freeze subd
8 tool>gemoerty>zremesher
9 tool>gemoerty UN-freeze subd

@informerman: That was exactly what I was asking for! Thanks! I hope my CPU won’t get burn while making this kind of operations!
