Pricing is always difficult and you never really know if you got it right, I tend to take advice from TGC as they have more experience than me.

The only reason I decided to write this was because it seemed the character controller and vehicles were not straight forward in Dark Physics.
I have also taken a slightly different route with Dynamix. It seems Dark Physics tried to do more for you, such as set up the vehicles/ragdolls or render the fluids in an attempt to make things really easy for the user. This was well intentioned and perhaps makes sense when creating a plugin for a basic language, but I think people quickly want more control and I have tried to keep that in mind while trying to keep it as simple as possible.
So as far as fluids/particles go, Dynamix does not render them for you since rendering has no place in PhysX and it's probably the same with most physics engines. That said, I have put in commands to make it easy to sync objects to the particles, I am also looking to help people have everything they need for different rendering techniques.
You only have to google around to see how many different methods there are for rendering fluids, some highly realistic(and complex) but not possible in a real time game, others less convincing but fast and easier to set up.
So I will provide commands for you to retrieve fluid particles positions and remaining life and you can render them however you wish, and as mentioned, there are some commands to make it easy to sync objects to your the particles but this will not be the most efficient method.
