fixed particle id

Recommended Posts

hola,

i'm copying box and a sphere to particles and using copy stamp in order to randomize their scale.

(rand($PT+215))

i'm watching my particles as they travel ,their point numbers are changing. so my expression returns diffrent result at every frame , so overall effect is look jittering. any idea how to fix?

You use @ to work with variables in Group parameter fields and in Wrangle fields where you are writing vex.

 

Use $ to work with variables in SOP parameters directly (excluding group parameters) where you are using hscript.
