Top Tip Tuesday - Particle Constraints Mapping

In Top Tip Tuesday this week, we connect particles with dynamic springs, using a Birth layer in nxConstraints. A shader is used to color the particles with black-and-white values, driving the breaking of the birth constraints using data mapping. The result is a highly dynamic and energetic particle simulation with springs connecting black particles breaking immediately and those connecting the white particles staying intact.

Fantastic one, Bob!

[@ExpressoMechanicTV]

Great stuff - thanks for sharing!

[@ckhmod]

Would you guys ever do an add on where the white, for example, could be a gelatinous / viscous and the black could be another type of material, for example, a gold flake? Or would that be separate emitter builds? Curious how that would be built and textured in Octane.

[@RadGnarRad]

Two emitter builds... yeah the particles may not interact - but it'd be just as easy and allow you more control. Plus, you could easily use a separate texture. Bob would know how to get the particles to interact, but I am le tired and gonna go watch some TV. But yes your instinct is correct

[@thegreatszalam]

You can use the particle color to move between any number of materials in one particle system. I'm not familiar enough with Octane to walk you through the steps, but it's really easy in Redshift.

really cool technique. 👌
