I am trying to use the distance of each particle from the source as a parameter to determinate its color through a gradient. This is how I am using the nodes in Unity's VFX Graph
However, even if I use the result of the "lenght" node directly into "Set size" node nothing is being rendered. I assume that the substract operation returns (0,0,0). If thats the case, then how this operation should be done? Is there a node that already does the job?
