PhysX Extensions
Nodes from this group allow artists to work with GPU-accelerated PhysX liquids directly inside 3ds Max. Each liquid simulation requires a PhysX Sim node, which can interact with other rigid bodies present within the PhysX simulation. To create a liquid simulation, the user also needs the PBD Liquid Sim node, PBD Liquid Phase node, and PBD Source node.
It is important to note that liquid can be retimed while PhysX does not provide sufficient foam information to allow retiming.
If you're starting from scratch, select the object in the 3ds Max viewport that you want water to emit from. Right-click inside NodeWorks and choose Quick Presets -> PhysX PBD Liquid. This preset will create and connect all the nodes required for a basic liquid setup.
PBD Liquids support only nVidia Pascal architecture and newer. GTX 10xx and newer card is required.
Please make sure that you always have the latest nVidia drivers installed.
