Scale particle emission rate using vertex color

I have edited "simulate_particles" compound.
you can use a vertex color to scale the "emission rate" and "initial velocity" on parts of the surface.

I expect Autodesk to support texture maps in the future.

a vary_source_properties could do the same thing with color set , as u said down side is texture maping-

but i liked what u did with other nodes however i dont understand it attall :)))

it would be nice if u explain logic behind your graph why there are values why there are set and get in a word why nodes are there

and yes for sure this bifrost need lot more tools and utilities to get in work

for now i think practicing is kinda waste of time

I understood " vary_source_properties" .

I edited "simulate_particles -> solve_particles -> advance_one_frame -> advance_one_timestep -> emit_from_source -> emit -> create_points "

example1 : use the feedback port .

example2 : use influence

example3 : edit simulate_particles
