Because Michal Fratczak build some time ago a procedural primitive to load and render particle caches with 3delight i started to play around with it and got it implemented in my plugin.
but because its no fun to work with something you cant see, i started to code a node which reads the particle cache and displays the particles in the OpenGl viewport. this is now in a very early stage but it does basicly what it should.
(this shows the viewport particles and a render from fusions internal OpenGl render, therefor the Replicate3d node)
the rendering via the 3delight procedural is really fast and looks like this:
maybe next time i got it more stable and with some more options, so you can play around with it
