Atom Posted June 16, 2017 Share Posted June 16, 2017 Hi All, I have a pyro sim where particles are stamped out as fuel. What I would like to do is to link some of the pyro solver parameters to the age of the particles. For instance Gas Release increases as the fuel ages? Is this possible using the H16 pyro solver? In this image I have hand animated the Gas Release and Smoke Amount to increase when the dragon finishes spitting out the fuel. However, the dragon head is immediately engulfed in flames when the increase occurs. If I could scale these amounts by particle age, I think I could avoid this problem...

Pazuzu Posted June 16, 2017 Share Posted June 16, 2017 Sure you can! The nice thing about pyro is that the combustion model is a post computation (but by default you can't accumulate divergence aka "Gas Release", because there is a cleaning before the combustion model), so you can create an ad-hoc scalar field to then sample your age out of your particles to use as a factor for the divergence to control the expansion/contraction of your sim in a per particle basis. But I think also that the divergence is not the only problem, I think you should also control or force the fuel to die with the same "age" field, to have even more control or shaping of your sim.
