dreamblk Posted June 13, 2021 Share Posted June 13, 2021 Hi New to Houdini How do I constrain the axis on particles. I want to constrain the z-axis to ) and have them float and move only on the X and y-axis ( see attached) particle_constrain_Z_axis.hiplc Quote Link to comment Share on other sites More sharing options...
Dweeble Posted June 14, 2021 Share Posted June 14, 2021 You can use a POP Wrangle to force positions to zero. Alternatively in your setup POP Steer Wander can be set to be 2 dimensional, and in the POP Source your particles are receiving varying velocities on the attributes tab. Fixing both of those will keep your particles to Z so long as you don't introduce velocity anywhere else. Quote Link to comment Share on other sites More sharing options...
