I'm trying to get a starfield effect going, where you'll hopefully be able to eventually fly through it, literally (not just the illusion). I've made the following class trying to get the ...

I'm at a loss for what the issue is, as it seems to be happening rather deep in the Flint code. Perhaps there's a confusion between Flint's Particle object and Papervision3D's? I'm using the current version of Flint (from teh downloads page) and the trunk code of Papervision. Either way, if someone gets the following code to run, I will be excited.

Hi You need to define a 3D object for PV3D to use when rendering the particles. e.g. these two lines from the BrownianMotion example define a grey circle as the 3D ...
