reference

I chose this video as my reference because it is a great combination of particles, pyro, and RBD simulation.

nodes

animated mountain/ velocity

I added a mountain node under the sphere and animated the amplitude to creat a explotion-like effect. Add trail node to compute velocity then it can be brought into dopnet with particles.

particle sim

dopnet

popwind

Vex was used to randomize the air resistance by ID.

second dopnet

pop replicate

popreplicate was used to generate a spreading trail. The velocity stretch controls the length of the tail.

trail

add Cd and Alpha to points

Color will be brighter and Alpha will be lowered while particles age.

particle shader

mtlsGeomPropValue can read attributes from point, but be advised that some attribute names are different from which in SOP. For instence Alpha in here is called displayOpacity. Read it and assign it to emission and opacity of the particles.

particle render

Now particle is glowing and dissipating along with age.
