It does support them ( shadeC evo ).
Add this to your main function:
sc_screen_default.settings.forward.enabled = 1; //enable if you need particles or custom materials which can't be rendered in the deferred pipeline
sc_screen_default.settings.refract.enabled = 1; //enable for refractive effects such as heat haze and glass
I used EVO with flame particles etc, worked "well".
