One of the big features of the S2 Engine is the use of NVIDIA PhysX for the physics sub-system.
The S2 Engine also offers a scripting language but it’s not specified which scripting language it is: Lua, Python, Basic-based, or customized language?
The shadows are based on stencil shadow volumes (doom 3) but real soft shadows based on shadow mapping don’t seem to be supported (from the website: Soft shadows can also been simulated via projective lights. – Thanks ca$per 😉 ).
Anyway, graphics rendering looks cool (thanks to post-processing 😉 )
The prices of S2 Engine range from 135 euros to 5730 euros.
E come si dice: in bocca al lupo con sto engine!
