Vertex Animations and Cascade, not starting on frame 1

KKValentin

Hey Everyone!

I'm wokring on a particle effect and I'm trying to use Vertex animations in UE4.9. I've got my material set up and it is working fine, but when it's implemented in Cascade and the particle plays, it doesn't always start on frame 1. Essentially, the effect is a bunch of bombs fly out from a center point and hit the ground, but sometimes they will just spawn already on the floor? And sometimes they will start on the floor (or some random frame) then reset at frame 1 half way through the particles lifetime? 

The whole animation is only 17 frames, does anyone know how to fix this, or has anyone else encountered this problem?

are you by any chance using the time node to drive the animation and not the particle relative time?

I was, yeah. I got some other feedback instructing me to look into dynamic parameter nodes to control the animations, so we'll see how that goes. But I actually ended up discarding the vertex animations for the moment, I didn't have enough time for the R&D required to learn lol
