Object Attribute Handler
Color attributes, float masks, and transfers on objects — plus a cleanup for unused vertex groups.
Once a mesh carries color attributes and masks for geometry nodes or GLB, the data becomes the production. Copying it by hand between objects, or leaving empty vertex groups in the file, is how the next export surprises you.
What it does
The handler adds color attributes (including float-mask attributes), selects faces by mask, paints a unique float mask per face, copy/pastes mask labels, sets GeoNodes values, builds mask combos, and transfers colors from the active object to the selected ones.
A smaller sibling operator removes vertex groups that have no weights. Same instinct: stop carrying dead data into the next file.
What I do not claim
I did not write Geometry Nodes as a product. This tool talks to attributes the file already needs. Artists still decide what the masks mean.
