Howdy, Ive always liked the paint select feature in Maya, so I made it one for max.
Consider this v0.01, it only works in face mode in editable polys. It functions like a toggle, run the macro once to turn on paitning, run it again when done.
Bind it to a hotkey.
Wider support for selecting stuff is hopefully on the way.. Not sure if ill be able to get it to work without making the script too laggy, but ill update here if i do.
