Help with v for moving particles in PopNet
Hi all, I'm new to Houdini yes, but not to the VFX industry!
Wondering if anyone knows a quick fix for this. Basically, my animation is an alembic import which doesn't carry velocity. While trying to calculate this velocity I was told to use the trail node, but the moment I use it, it somehow throws off the angle of my particle emissions.
My particles should be moving forward with the animation (which is why I need the value), which the trail node actually helps with BUT throws off completely the angle..
Anyone either knows a way to fix this angle issue? Or simply another way to calculate the velocity that wouldn't change the orientation of the spray?
Thank you for any help
