Radius For Tube Particles Per Particle

[yawzer]

hello guys,

I'm trying to generate tube particles that will grow over time.

I can't even add radius0 and radius1 as general attributes to my particle.

i get - Error: Found no valid items to add the attribute to.

so..maybe its so basic its not listed elsewhere online, but i can't figure out any more info as to what i need to do to get this working..

i tried adding an expression into radius1 of the Render Attributes.

creation: particleShape1.radius1 = .02
runtime: particleShape1.radius1 += .0005

but this just makes all the particles creation size gradually get bigger. (and strangely caps off around .737 )

any insight would be appreciated.

thanks!

All attributes that affect the individual particle have PP in their surname.

Unfortunately theres no radius1 and radius0 PP attributes.

ohhh durrr that makes sense..

so theres no way to control the individual radii of tube particles?
