Scattering Phoenix sims

[johnnelsonvfx]

Hey Artist.

My team and i have a interesting problem where we need to set a large forest on fire. Trying to think of solutions that will be renderable. One solution is scattering a Phoenix fd Fire simulation utilizing the same Distribution as the tree (Forest Pro). This is a large areal shot that has a lot of trees on fire in it.
One solution is scattering cards of fire on the trees for the desired result. We would prefer a sim cached rather the an image sequence. Does anyone have ideas on this or know if scattering phoenix fd sims with a software like Forest Pack would work.

thank you

One idea: I haven't used forest pack but does it provide individual transforms (pos/rot) for scattered trees after the scatter is complete? If so, it would be pretty quick to write a script to distribute volume loaders aligning to those transforms. You could also add in a random offset for the cache frame so the whole forest fire could be mainly a single, longer sim.

I am not sure if that data can be extracted from the forest pack. It will be a avenue that i can look into. Thank you

If not, perhaps you can scatter points in the same way using forest pack then align to those? I probably should have looked into how forest pack works before I commented, sorry I'm not more help. Best of luck

can volume grids be instanced in 3.6?

Hello,

This is still in the to do list I'm afraid.
