How scale point based on vertex paint with a scatter by number

Hello everybody,

 

I'm new to bifrost and I need your help. I ll try to change the size of scattered point with a vertex paint. 

I ve tried to use a "get geo colorset" plugged in a "vector to scalar" plugged into weight of a "scale point" with no result.

 

Any idea 

 

Loic

Make sure you are reading the color set correctly and make sure that the data type is correct as well. Usually is float 4. To make sure press W to see between the connections to see what type is it

Hello,

 

Thx for your answer. I'd already tried and setup all the node. It works when connect them into density but I don't know how to setup for my need. Is it possible for you to post here a scene or a tuto to drive a point scale base on a vertex paint ? To drive scale instances. Thx for your help
