This node generates point geometry from a height field.
The node will only scatter points where the Scatter amount layer is on. If the layer is empty, or the parameter is left blank, the node won’t create any points at all.
Scatter Amount Layer
The name of a mask layer specifying which areas of the height field will get scattered points.
Use Exact Point Count
Specify the exact number of points to generate, rather than a density value.
When Use exact point count is on, the number of points to generate.
When Use exact point count is off, the number of points per square meter to generate.
Pushes points away from each other as a secondary step, to prevent clumping.
When Relax points is on, the number of iterations of relaxation to do. More iterations will more evenly distribute the points, but can be slower, and after a certain number of iterations that evenly distribute the points, more iterations is wasted effort.
Scale Radii By
When Relax points is on, scale point radii by this amount before relaxing. A value less than 1 will increase clumping. A value of 0 does no relaxation. A value greater than 1 may speed up convergence of the relaxation when scattered points are very far apart.
Use Max Relax Radius
Prevent far-flung outlier points from affecting relaxation.
Max Relax Radius
Points this far from other points are not included in relaxation. Decrease this if outlier points in low-density areas are causing problems with relaxation.
Seed for the random number generator. Using the same seed always produces the same scattering. For example, you can change the value to get a different scattering, or set it
$F to get a different scattering on every frame.
An optional hard limit on the number of points to generate, to prevent accidents where you mistype a value and Houdini tries to generate a ridiculous number of points that locks up the computer.
