Naiad Sand tut

Following up the sand RD i did recently with naiad - heres a quick tutorial/overview about how the setup works via creating our own particle channels, splatting to fields, generating UV's and some pros & con's with using the particle detail node to increase detail.

Naiad Sand RD

I was making another ident thing in collaboration with Man vs Machine recently and it called for a big egg made out of coloured layers of sand to fall/collapse to the ground.

Sand is always tricky - perhaps more so than water and fluid simulations - as it moves and flows like fluid but has friction and rigid body bahavior per-particle.  This means when you are dealing with MILLIONS of particles - things can get pretty difficult to control and simulate.

I decided to pursue a solution with Naiad - utilising alot of custom channel controls to try and get the volume of sand to collapse in chunks and settle quickly.

Heres some R&D I was playing with early on as a proof of concept.  I was combining massive viscosity values and creating multiple particle tags via lots of small fractured bits of geometry.

I plan to put together a more indepth look at this stuff soon
