Removing editing at higher subdivs?

ZBrush Usage Questions
#1

I’m stuck.

I have a model, a dragon style wing (see attachment) down at subdiv 5.

Due (I think) to some ill-advised manipluation/posing at low-res, the
high subdivs have been somewhat messed up in places. polys now
intersect and overlap (1). I really don’t know what caused the problem.

What I want to do is (say) keep subdiv 1 or 2 untouched, but in specific areas only, revert higher subdivs back to the ‘unedited state’. Or the
state they would be in if I had just subdivided the mesh from L1 to L5.

Last time I got into this problem, I dropped down to a ‘clean subdiv’, saved
a morph target and applied the smooth brush at highest subdiv to the
problem area. Then I dropped back down and switched back to the saved
MT (to restore the good low res mesh) and I was in good shape.

But if I try that in this case i get (3). Worse than my starting point.

Does anyone have any advice on how to fix hi-res problems like this?
I’ve tried simply smoothing them out, but haven’t had much success there
either, the intersecting meshes seem to confuse the smooth tool.

What I’d do is this:

  1. Back up your mesh in case of unexpected occurrences. :slight_smile:

  2. Clone the mesh and append the clone as a new subtool to the original mesh.

  3. Go to the lowest subdivision level of the clone and delete the higher levels.

  4. Subdivide the clone back up to the same level as the original.

  5. Store a Morph Target for the clone at the highest level.

  6. With both the original mesh visible and the clone the selected subtool, press Tool>SubTool>Project All.

  7. Using the Morph Brush, restore the problem areas to their pre-project all state so you can then re-work them to your satisfaction.

HTH,

Thanks Marcus, I’ll give it a go.
