Then there has to be another way to make dust if not with particles. Because I'm pretty sure at least the "What do I build comets out of?" question seems to have been answered by particles, as I managed to emit a comet tail, just needs some fixes.Yea for the particle stuff I suggest you concentrate on something else and take things slowly. If it was me I would emit a pmatterwave on a freeze node within TP and then have the emitter produce different scale and rotation values of sprites. Honestly the best way for me to do it is like I said before with Particular in AE. Problem is that C4D is the only app that talks directly with AE and can roundtrip. It is a beautiful thing...
So this is my project to tackle at the moment. should be able to have the whole thing modeled in a few hours. A little FA-18 that I can add to the collection. I love how people complain about C4D modeling and how it sucks. How so? It has all of the tools of the other packages. I think it is just that most suck at C4D instead...
Alternatively, I could just make cloud textures and play with transparency and make a space dust effect in the distance. But particles seem to be pretty fun, as they make clouds and I can control the particle size, just cannot freeze them (yet).
I was also thinking of working on yet another project (I bet some people here are like "Oh no!!!" after reading this). I want to re-build that flying saucer I made on 3ds max, only that I'll have to figure out a way to add a lot of gadgets in it (such as ability to turn into some kind of crab machine, take out laser guns, fire abduction beam and have 16 mobile cameras on top). Easier said than done though.
