Hi Nickolay,
I gave you the wrong info before. Nitrous (spherical) particles are only displayed in 3dsmax 2015 and newer. Since you're on 2014 it makes sense that it would display dots instead.
SDF with dynamic body type is the only way to have deforming collision geometry within the scene. If you collision object is not deforming (just moves/rotates) then you can also use Convex body type for it.
