attributes based on prefix

[Kenneth Polonski]

So I'm currently trying to find a nice fast way to export some user added attributes and values to a json file, based on their prefix of 'mtoa_' or 'mol_' in the attribute name. I actually have all this working just fine, but it takes quite some time to complete. The reason is that I'm currently iterating through all the shape nodes of a scene (2500+ shapes) and then for each node iterating through the attributes to see if the name contains the prefix. There must be a better way. It would be super cool if the pm.PyNode().hasAttr() method supported wildcards, which does not seem to be the case.

Does anyone have any suggestions for a better way to go about this?

Thanks!

Have you tried this approach through the Maya API to see if you get any better performance?

I have not but this seems like an excellent idea since I've never had to use the maya API before. Good learning opportunity! Thanks Justin

Were you originally using PyMEL for this? Have a go with maya.cmds too, it's probably much faster when iterating through nodes and attributes.

Yeah I was using pymel. Thanks for the suggestion! I'll give it a whirl with maya.cmds
