Importing Keyframe Animations

We are trying to get an animated particle system in Blender that is a constant number of triangles which would ideally be created in software outside of Blender. Any ideas?

We’re just looking to import keyframe animations from a
particle system “rasterized” out to just a mesh of triangles. It appears
that importing keyframe animations may have worked with some Blender
scripts in the past. Is that possible?

If anyone knows how to make this happen, it would help us get a start on our vfx.

Is this an emoticon of Mr. T? :ba:

His name is BA - the same as this forum. So yes it is Mr. T.

I moved this thread to Python & Plugins as this belongs to the importer scripts and is not BGE specific
