Is there a way ( weigh? ) to "append" weighting to bones/vertices versus overwriting ( as appears to be the default )?
Anybody? Anything? Please?????
no idea what your question means
well, By Default the weighting tool in pmxe will overwrite any weights assigned to any verts you brush over.
If you dont want to overwrite but add/subtract click the 'on' button in the spray box of the weight window.
If this is not what you wanted then i have no idea what your on about xD
