Anyone know how to go about getting all points sorted by their color into an id attribute? Thanks in advance.

Hi,

You can convert your colors into IDs like this using an Attribute Wrangle:

i@color = floor ( @Cd.r * 1e6 + @Cd.g * 1e3 + @Cd.b );

If you want to consolidate the IDs to be ordered without holes, you can add another wrangle like so:

int colors [ ] = uniquevals ( 0, "primitive", "color" );
@id = find ( colors, i@color );
