Here are some of the new features for this great destruction tool.
-More speed and smaller files when cache particles thanks to news in TP 5.1
-Dyn solver presets: Change on the fly dynamic solver quality/speed or turn it off.
-Gravity: Change direction rotating gravity object and animate it.
-Wind: Change direction rotating it.
-Atractor: Select strenght and time effect, and move Atractor object so frags will follow them.
-Use mesh for activators.
-Default ground is no more visible by default. Instead in general properties you can enable “ground” and your 3dsmax floor will act as a deflector for geometry and debries.
