Hi Folks-
There have been a few implementations of this kind of tool released over the years, here's another one.
The basic functionality is:
- Select an object with at least 1 weight map
- Run MCP>Select>Select From Weight Map
- Pick what kind of component you want to select (points, edges, polygons)
- Specify the weight map
- Select the selection rule (greater than, less than, in range)
- Move the slider
The main gist of this version of the tool is the interactive feedback, as you adjust the slider your selection result changes.
For convenience, I added some buttons to turn weight map display on/off in the currently focused viewport.
