Render simple smoke with tyFlow without Phoenix FD

[shadowkiller]

I know you mentioned no other software but there is a useful trick for speeding up rendering of point clouds (or just about anything really) and getting a smoother result. If you're renderer is rendering them as dots and is tied to you're resolution like Krakatoa is, you can render your frame at a lower resolution and then use an AI up-scaler to increase to full res. It is great if you need a smooth result without seeing individual dots. I used gigapixel from topaz.

Its no substitute for more particles of course, but it certainly helps when you starting getting highly diminished returns when adding more particles. It can also help smooth things out due to the adjustable filtering settings. Combining it with a motion blurred result can smooth things even more. I used it on this ink sim i did awhile ago.
