# nParticles Advanced Techniques

This tutorial shows you how to create the effect of molten metal being poured down a chute and into a collecting tub. The tutorial combines a number of different effects including three types of nParticle systems, an nParticle output mesh, a 3D fluid with container, and an external gravity field. You can use these components to create effects that combine nParticle systems and fluids such as lava flows, flowing liquids, or other effects.

To watch a video of the rendered simulation, open SlagPourFoundryFinal.mp4v, included with the tutorial lesson files.
