The LOP node whose stage is the source of the point instancer data.

The scene graph path(s) of one or more PointInstancer prims to import. Accepts pattern syntax and the /Path[start-end] id-range syntax for selecting a subset of instances from each instancer.

When on (the default), creates a path string point attribute holding the scene graph path of the source point instancer prim for each output point. This is what the PointInstancer LOP uses to map each modified point back to its instancer when several are being edited together.

When on (the default), creates a detail string-dictionary attribute named importedids that maps each source point instancer’s prim path to the array of ids that were imported from it. The PointInstancer LOP reads this map to compute which instance ids were removed from the SOP geometry, so it can apply the Missing Points Policy correctly.

When on (the default), creates a detail string-dictionary attribute named importedprimvars that maps each source point instancer’s prim path to the list of primvar names that were imported (or named via Common Primvars). The PointInstancer LOP uses this to drive sparse primvar resampling without re-reading the input stage.

When on, each output point’s position, orientation, and scale include the source instancer prim’s world transform. The same world transform is also recorded as a matrix4d point attribute named usdxform on every output point. The PointInstancer LOP reads the first point’s usdxform value to recover the world transform when writing the points back to USD, so the destination instancer prim ends up with the same world placement as the source.

When off (the default), each instance is left in its instancer-local frame.

When on (the default), import the source ids attribute as the id point attribute. Disabled when Invisible Ids is on, because that toggle implies ids must be imported as well.

When on (the default), create a usdvisibility string point attribute. Points whose id appears in the source instancer’s invisibleIds get the value invisible; all other points get the empty default (inherit semantics).

When on (the default), set each output point’s position P from the source instancer’s positions attribute.

When on (the default), set each output point’s orient attribute (quaternion) from the source instancer’s orientations (or orientationsf) attribute.

When on (the default), set each output point’s scale attribute from the source instancer’s scales attribute.

When on (the default), set each output point’s acceleration accel from the source instancer’s accelerations attribute.

When on (the default), set each output point’s velocity v from the source instancer’s velocities attribute.

When on (the default), set each output point’s angular velocity w from the source instancer’s angularVelocities attribute.

A whitespace-separated pattern of primvar names to import from the source instancer prim(s). Each matched primvar becomes a point attribute with one value per instance. The primvars: prefix is stripped from the resulting attribute name. The default * imports every authored primvar.

A whitespace-separated list of primvar names you want authored on every PointInstancer this node imports – and, by extension, on every instancer the downstream PointInstancer LOP writes back to. This is a finer-grained alternative to setting Missing Primvars Policy to Create on the LOP (which would broadcast every SOP primvar to every affected instancer); list only the primvars you want present everywhere and leave the rest to the per-instancer import set.

The list is appended to the per-instancer primvar entries in the importedprimvars detail attribute, which the LOP reads to drive sparse primvar resampling.

Only used when Imported Primvars Dictionary is on.

How prototype-index information is imported per point.

When Import Prototypes From is protoIndices Attribute, the name of the integer point attribute to create. Defaults to protoindex.

When Import Prototypes From is Prototype Prim Path or Prototype Prim Name, the name of the string point attribute to create. Defaults to protoname.

Imports each instance’s prototype bounding box, computed in the instance’s frame.

A comma-separated list of purpose tokens (default, render, proxy, guide) used when computing each instance’s bounding box from its prototype. The default default matches the default purpose only.

When Import Bounding Box is As Attribute or As Attribute and Packed Primitive, the name of the float-tuple-6 point attribute to create. Defaults to bounds.
