Superluminal just released Stardust 1.5. Stardust is a modular 3D particle system for After Effects.
The new update adds a new volumetric toolset based on OpenVDB format. So it is now possible to convert the particle systems into mesh volumes. It also features a new wireframe display mode for 3D geometry and an Extrude Edges command for extruding 3D forms from the edges of masks, and for generating 3D text.
