I've got this mildly annoying pipeline issue - I have particles exported out from another program as bgeo sequences, with all the correct point attributes set, and I'd like to just use a delayed-load-procedural to bring them straight in at render time.

The only problem is, the bgeos only contain points, they're not particle objects. I know this is as simple as loading them in and using an Add SOP with “Add Particle System”, but I don't want to have to load and recache them just for this.

Ordinarily I would just flick on “Render As Points” on the object, but I want them to render as sphere-primitive particles, not point-primitives.

Any way I can get around this? Is there a way of flagging an object to “Render As Point-Spheres”? Is there some clever point-attribute I could set to override the point-primitive type? Any cunning way to “Add Particle System” at render time?
