Audio to Animation: Opacity expression

Postby matt cass on 09/11/2018, 4:03 am

Hi all,

Hoping you can help with the below regarding the VCP audio to animation tutorial.

can anyone advise the best way to prevent the attached image from occurring? During dead air I get a unsightly line of particles emitting.

Is there anyway to add an expression for the particle opacity, so they are only visible at a certain particle speed? So they just appear when music is playing?


Any help would be much appreciated.
