Hi, 

I am creating as excercise a blendshape node inheriting from the 
MPxDeformerNode. I got it to work with 1 mesh as input, now I want to make 
it work with n inputs. I don't understand how to dynamically create 
attribute whose name is the name of the target. I mean if we have a maya 
blendshape, that is how it looks:

But when you then access the pSphere2 attribute you don't need to do 
blendShape1.weight.pSphere1 but simply blendShape1.pSphere1.

If I query the type of the attribute weight it is a TDataCompound. 

I guess this is something that does not need to happen in the initialize of 
the plugin but rather creating a command that handles it in the doIt, 
redoIt etc and having some methods like addTarget and so on, right? If 
anyone could share some snippet or a little explanation on how to do it 
would be really appreciated!

Thanks,
Daniele
