A LITTLE PARTICLE STREAM
This is a beginner tutorial. Actually it is a very old tutorial that I did not create (kudos to whoever created it). I modified it for H16 and then added a particle network and COPs. OK, what's in it? You will learn about Point and Primitive attributes. Using the Particle SOP and the Primitive SOP. Learn how to create an inline DOPnetwork from scratch. Create point attributes to sort all the particles by emitter point and create curves. Render it out and bring it back onto COPs. Use the COP VOP generator to create a grid and moving cloud noise. Create a basic blur and then of course composite it all together.
