thanks a lot! Thats helps a lot! I did it this way. Works with sprites ans defaults. It keeps the ratio and do a nice random between the particle pictures.
Would be great to a a little script running loading it by itself from a specific folder. But yeah, fair enough : ): )
The quality of the small particle pictures doesnt look good. Lots of aliasing and noise. I (maybe) understand the aliasing , but where is the noise coming from? Its getting better as bigger I scale each compo. (see above) Is they any way to "clean it up"?
I allready tried to increase the Quality setting from the compo from "automatic" to "Multi Sampling 64" as well the GPU Setting "Multi Sampling 64" that doesnt help. ANy idea on that?
