glu3D is a complete system that makes easy making liquids in Autodesk's 3dsMax, Maya and XSI. glu3D uses particles to simulate the liquid behavior, and a multi-resolution polygonal surface is also generated to display the liquid surface.
Pwrapper is a surface blobMesh generator for any kind of particle system in 3dsMax, Maya and XSI(not only glu3D particles). Create a new instance of Pwrapper. Then select any particle system through pwrapper command panel and its particles will be wrapped with a poly surface mesh. Modify Pwrapper parameters to change surface look.
