point instancer
This node controls the PointInstancer display method. ATTENTION!: omni.particle.system.core is currently undergoing extensive (breaking) changes. Please be aware that systems built with the existing extension will need to be rebuilt in the USD Composer 2023.2 release.
Installation
To use this Node, you must enable omni.particle.system.core
in the Extension Manager.
Inputs
Name |
Type |
Description |
Default |
---|---|---|---|
active |
|
Is the point instancer node currently active? |
True |
aim |
|
Aim points the particle in a specific direction in x,y,z. |
[0, 0, 0] |
faceActiveCamera |
|
If this is on, the y axis of the geometry being instanced will face the camera for each instance. Turn this off if you want the particle or shape to use its local orientations. |
True |
orientWithActiveCamera |
|
If this is on, the y axis of the geometry being instanced will face the camera for each instance, and the x axis of the geometry will be vertical relative to the camera. Turn this off if you want the particle or shape to use its local orientations. When this is on, faceActiveCamera is ignored. |
True |
rotation |
|
Rotate the particle or shape in X Y Z. |
[0, 0, 0] |
up |
|
Change the ‘top’ value of the particle in x, Y, Z. |
[0, 0, 0] |
scaleMultiplier |
|
Multiply the Particle Size in X, Y, Z. |
[1, 1, 1] |
filterObjectIndex |
|
When this is non-negative, geometry will only be instanced on particles with this object index. |
-1 |
particles |
|
Input particle data, including aim, up, and rotation. |
|
points |
|
Input points data, including rotation, scale, object index, normal, tangent and binormal. |
|
prototypes |
|
Input prototypes. The connected prim(s) will be forwarded to the output PointInstancer prim’s prototypes relationship.’ |
|
prototypePath |
|
Input prototype prim paths. The connected prim(s) will be forwarded to the output PointInstancer prim’s prototypes relationship. |
|
inheritParentTransform |
|
If true, point positions will be written to the specified output prim(s) directly (thus, any transform on the output prim will affect the points) If false, point positions will be transformed into the output prim’s local space (thus, they will appear in the same location regardless of the output prim’s transform) |
True |
outputPointInstancerPath |
|
Prim path where the mesh should be output |
|
writeToSessionLayer |
|
Update changing particle transforms on the session layer instead of the authoring layer. |
True |
