Particle fluid tips

Particle fluid tips If a collision/container wall is too thin, the particles can collide with the wall but the pressure solve step may not see it, causing particles to “stack up” against the wall instead of bouncing off it, making the liquid appear to compress and disappear. Increasing the thickness of the collision geometry will … Read more Particle fluid tips

Gas Up Res

This solver can scale a low-resolution smoke, file, or even liquid simulation into a higher-resolution container. You can add detail with turbulent noise, at a small enough scale to not affect the large-scale motion of the smoke. This lets you set up the general motion of a simulation at a low resolution and then create … Read more Gas Up Res

POP Collision Behavior

The POP Collision Behavior node performs operations based on collisions set in the hit attributes. Source: POP Collision Behavior Typically, the POP Collision Detect node is used to do both the collision detection and resolution. However, this node can be useful when responding to DOP collisions created by the Add Hit Attributesoption of the POP Solver. This operator modifies … Read more POP Collision Behavior
