Re: Merging Meshes & Transferring Weights takes forever

[Jason S]

Don't know what is involved for implementation, but here's the best 'NumPy' description I found from here http://ipython-books.github.io/featured-01/ which also includes further optimisation tricks/recipies Featured Recipe #1: Getting the Best Performance out of NumPy NumPy is the cornerstone of the scientific Python software stack. It provides a special data type optimized for vector computations, the ndarray. This object is at the core of most algorithms in scientific numerical computing. With NumPy arrays, you can achieve significant performance speedups over native Python, particularly when your computations follow the Single Instruction, Multiple Data (SIMD) paradigm.

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 weights. Something like ~26hrs sometimes. That set has 436 objects (small and large volume) with a total of 161,074 points and 172 deformers. I'm using the built in Merge command and attribute transfer commands. Does anyone have a better way to get the weights over? GATOR seems to be using the same if not an even less efficient method to do the transfer so that's not an option (I think the default tool uses it anyway). I'm open to using Maya if someone knows a good tool / script for doing this without having to spend ages figuring out how to do it. As always, any help is appreciated. Eric T.
