3ds max forces

 

 

With this node user can apply various 3ds max forces to the particle system. Unfortunately, 3ds max forces are not multithreaded so their performance will be poor. Keep in mind that this is a force where heavier particles accelerate slower than lighter ones.

It accepts particles, positions of voxel grid as input.

 

[Inputs]

 

#Particle Stream - This pin requires a particle stream to be connected. Connection is usually not required if any of the attributes is connected.

 

Enabled - Enable or disable node evaluation.

 

#Input (Position) - This pin requires position to be connected and the force will be calculated at that position.

 

#Input (Grid) ??? Calculate force over the entire voxel grid. This operation is faster than applying force on a voxel-by-voxel basis.

 

Note: If Input (Position) is connected then the particle will not be moved by the force. This is useful if user wants to do additional calculations by using the Force output value and does not want particle to be affected immediately.

 

Force Scale - Uniform scale of the calculated force.

 

 

Grid Properties

This rollout becomes available when voxel grid is connected to the Grid input.

 

Use Smoke ??? Enable this option is you want force to be computed only in voxels with smoke present.

 

Use Fire ??? Enable this option is you want force to be computed only in voxels with fire present.

 

Use Temperature ??? Enable this option is you want force to be computed only in voxels with temperature present.

 

Entire Grid ??? Enabling this option overrides all three previous options. Force will be calculated for all grid voxels regardless of the voxel content.

 

 

[Outputs]

 

Force - Outputs the sum of all forces.
