Just to update everyone. The Softimage RemoveFlexEnv() command is super
slow. The better approach is to get the weights array, iterate over
that cleaning out deformers that you don't need while keeping the
removal of deformer arrays and the removal of the unused deformers from
their respective
This may be an obvious thing, Eric, but did you try the closest vertex
method? Since you're transferring from the same exact shape, it should be a
lot faster than the default closest surface.

Thanks Matt,
You've summed it up quite well. I can't strip any more deformers than I
already have.
Alan, I'm not using GATOR and thus in the MergeMesh PPG it doesn't show
the method it is using. I'm hoping it is using closest vertex.

Hey all,
Running into a problem lately and it's becoming really problematic in
production. I have a rigged model with a ton of meshes (985) which are
all skinned. I have to combine a bunch of these based on predefined
groups I've made.
However it's taking forever to combine and transfer

How does this help when having to transfer weights of many meshes and
their points to a coinciding point on a merged mesh?

Yeah these general responses of 'just use numpy' aren't really in the
vacinity of providing me any path forward.
I know what numpy is but this suggestion somewhat implies that I should
write my own GATOR tool, which I have no interest or time to do.
I wish simply doing an:

Hi Eric,
A couple of things to keep in mind (I'm sure you already went over these,
but just in case):
- Merge is expensive, make sure to merge your groups at once instead of add
part by part through multiple merge operations.
- Transfer weights from a single cage mesh works way better than from
Thanks Cesar,
The merge itself is relatively fast. Transferring the attributes is
what is slow. UVs are super quick but skinning is the culprit. I don't
have a low res cage as I need to maintain the weighting that is there
pretty much 1 to 1. What is appearing to be the problem is that there

You’ll get the best results if you merge the meshes first, cull redundant
deformers from the envelope, then do the weight transfer. The part that’s
taking so long is you’re creating an M x N x O array of deformers and vertices
(436 objects * 161,000 vertices * NbDeformers). That’s a huge
