FubaR: Well, I pretty much use all the different tools in Maya. Fluids for the ocean and some clouds, particles for smoke and tracers. Im not sure actually what , could you be more specific?? Sorry...

pbman: Thanks! The propeller is actually a fake one... Let me show you the mesh. Its quite diffecult to get the propeller to look right when you have a propper mesh. I've tried different motionblur settings and different rotation speed but could get it to look right... this isn't perfect in any way but at least it gives the illusion!
