sim bounding box of pyro trails

Recommended Posts

hey

I'm trying to set up a missile trail, and started from the shelf tool I encountered an issue due to a strong wind I'm applying. basically the sim is going out of the bbox of each segment of the trail. Is there any way of letting the sim going out of the original bbox size?

cheers!

Do you have a dynamic fluid resize node plugged into input 2 of the pyrosolver?

This is clustering right?

yup, clustering, and yes there's a resize, I found out the size of each is driven by the scale attribute of the points created for the clustering, so plugging a wrangle to that you can increase the size of each cluster, so I made it bigger as needed...the resize has a delay otherwise the sim won't pick up correctly the emitter. so I activate the resize right after the emission is completed. This kinda work, maybe there's a smarter solution

on the gasResizeFluidDynamic DOP node, go to "Max Bounds" and untick "Clamp to Maximum Size"
you could also make your own resize setup using a SopSolver and a GasResize DOP.

hope that helps
