Maximilian Schönherr shows how to have particles emit particles using Maya Bifrost Graph.
Bifrost is relatively new, and while some things are challenging, some things are pretty simple, like scattering and FX, such as particles.
This latest tutorial from Uhr (Maximilian Schönherr) shows how you can have Bifrost particles emit other particles. You might remember this as a simple technique when working with Maya’s nParticle system. Schönherr shows how to do something similar by using two basic particles graphs in the Bifrost graph.
