particle flow - scale particle by speed

[stevesideas]

Do any of you script guys know how to do this ?

I found this:

http://www.scriptspot.com/bobo/mxs5/...y_velocity.htm

I might be able to change the length to scale....

[instinct]

add a scriptmodifier and use the following script instead of the default one:

on ChannelsUsed pCont do
(
	 pCont.useSpeed = true
	 pCont.useScale = true
)

on Init pCont do 
(
 
)

on Proceed pCont do 
(
	count = pCont.NumParticles()


	for i in 1 to count do
	(
		pCont.particleIndex = i
		mult =10
		pCont.particleScale = (length pCont.particleSpeed)*mult
	)
)

on Release pCont do 
(
 
)

change the mult value as a multiplier for the size. you can of course also tweak the line below the mult=10 to tweak the mapping of speed -> scale

Works like a charm ! Thanks

wow this is really useful, thank you!
i wish i could script myself.

[stevesideas]

I can script to an extent but sometimes its easier to ask than spend hours trying to work through something like that..

For particle related stuff like this i can really recommend Oleg's PFlow Tools Box#3 wich is basically like scripting, but visual and a LOT faster then script operators.
