hi, is there an easy setup to trigger, by an event (like speed >0.1) a timer from 0-1 over 10frames (inside a vopsop) ??

Is this possible without a sopsolver?
thanks, tom.

Maybe Attribute Fade SOP [sidefx.com] would do the trick?

hey cool…its sounds goood. i love when it appears a sopnode out of the dark and doing what you want

…BUT a vopsop solution would be nicer, because i want to drive a mix-node with two vector, which i want happens after specific condition. i.e. at frame 10 the condition happens and the a counter start from 0-1 over 5 frames. I tried with a simple fit-node somthing fit($F, triggerstart, triggerstart+blendingduration, 0,1)

the problem, which i cant solve it with SIMPLE solution, is to save a attribute (triggerstartframe) at specifiv frame “forever”.

If AttribFade doesn't work asi-is, you could always copy the VOP nodes it's using inside and adapt them to your needs.

ahh..cool its a vopsop inside. thanks!!
