Setting up the simulation

Before starting the lesson, set up the simulation by doing the following:

1. Open SlagPourFoundry_3.mb.
2. Hide the fluid_slag_smoke object by selecting it in the Outliner and selecting Display > Hide > Hide Selection.

   Hiding the fluid object speeds up the simulation while you add and adjust new components.

3. Turn off Intermediate object on the nParticle_slag object. To do this, in the Outliner, select nParticle_slag, and in the Object Display section of the nParticle_slagShape Attribute Editor, turn off Intermediate Object.

   You need to select this object for the collision event and to add nConstraints.

4. If you cached the nParticle_slag object in the previous lesson, disable the cache by selecting the nParticle_slag in the Outliner, and selecting nCache > Disable All Caches On Selected.

   Disabling the cache allows you to make changes on the nParticle_slagShape node, such as creating a collision event with this object.
