yujiyuji Posted July 13, 2021 Share Posted July 13, 2021 I'm now thinking of creating an effect where the inflating balloon breaks and smoke leaks out of the balloon. However, when I simulate the balloon as vellum, the static object doesn't work properly. Does anyone know a good way to do this? Also, does anyone have a sample hip? Thanks in advance.

Mozzarino Posted July 13, 2021 Share Posted July 13, 2021 In your case I would try to do two separate simulations. First the vellum of the balloon breaking and then the pyro sim. What exactly do you mean by "the static object doesn't work properly"? Could you post a flipbook or something similar so we can see what is going on?

yujiyuji Posted July 14, 2021 Author Share Posted July 14, 2021 Thanks so much for getting back to me! I've already done two simulations. I want to generate smoke inside the balloon and use the balloon as a collision. I am trying to make the smoke stay inside the balloon until the balloon breaks, and as soon as it breaks, the smoke will flood out from inside.

Mozzarino Posted July 14, 2021 Share Posted July 14, 2021 And where exactly are you having trouble? Could you show a wip? Maybe I can help, but I need something to work with.... Quote Link to comment Share on other sites More sharing options...
yujiyuji Posted July 15, 2021 Author Share Posted July 15, 2021 This is the hip file I tentatively created. Please check it.test.hip Quote Link to comment Share on other sites More sharing options...
Mozzarino Posted July 15, 2021 Share Posted July 15, 2021 I have attached some changes to your setup that were causing the problems in your smoke sim. You now have to art direct your smoke to escape from the holes created by the vellum sim. test_debug.hip 1 Quote Link to comment Share on other sites More sharing options...
