In this presentation, Urban showcases a few different ways of setting up emitters for explosions and develop a simple scatter shader for full control when rendering with Karma. These workflows will provide art-directable control over the pyrotechnics including explosion art direction, shaders, shapes, and principles.

Hi Urban thanks for the amazing tips, this is such a great workflow! Very keen to give this grain emission explosion method a try.
You mention around 19:00 mins you'd be able to pass this emitter setup along to us for a deeper dive inside your workflow. I'd love to get a stronger understanding of some of the sections you skipped over if possible?

Hey Urban, just curious...
Are you planing, at some point in a near or distant future, to make an explosion that actually looks decent ?
