Object Merge surface node

The source geometry can be transformed to account for differences between the source object’s orientation and a reference orientation. None will prevent any corrective transform from being done. Into This Object will ensure the object has difference between the source object and this object’s transforms applied. Into Specified Object will use the specified transform object rather than this object as the destination space.

The object to transform the other objects relative to.

• Leave the field blank to import the geometry into the current object's space. The geometry will appear at the origin with no transformation.

• Enter . to import the geometry using the transforms from the source object. The geometry will appear in its original position and orientation, but with zeroed transforms.

• Enter the path of another object to import the geometry in the context of that object.

Creates a point group for every object that is merged in. Each group name is made unique by appending a number if necessary.

When generating names for new point groups containing the imported geometry, add this prefix. This makes it easier to identify the groups created by this merge.

Creates a primitive group for every object that is merged in. Each group is made unique by appending a number if necessary.

When generating names for new primitive groups containing the imported geometry, add this prefix. This makes it easier to identify the groups created by this merge.

Creates an attribute named objname on the imported points, containing the full path to the source from which the point was merged in. If a point is merged from DOPs , the path is the path to the DOP Geometry Data.

You can use this attribute in later point expressions as OBJNAME.

Creates an attribute named objname on the imported primitives, containing the full path to the source from which the primitive was merged in. If a primitive is merged from DOPs , the path is the path to the DOP Geometry Data.

You can use this attribute in later primitive expressions as OBJNAME.

The number of object merge parameters available.

Controls whether the node uses this line. This can be useful if you only want to temporarily disable a merge instead of removing it completely.

A path to geometry to merge. Click the button at the end of the text box to choose a node, or type a path manually.

See the surface node help for an explanation of display and render flags.

• Choose an object to merge in the object’s geometry. For example, obj/model1. The Houdini uses the SOP with the display flag for display and the SOP with the render flag for rendering.

• Use wildcards to merge in multiple objects. For example, /obj/ball* would merge in geometry from any objects whose names start with ball. The wildcards available are the same as in the opglob command.

• Use a bundle reference (for example, @props) to merge in the geometry from all objects in a bundle .

• Choose a SOP node to merge in that node’s geometry, even if it doesn’t have the display flag.

• Use a dynamics path to merge in geometry from a dynamics simulation. For example, /obj/dopnet1:wireobject1/Geometry.

• If the path is blank, Houdini doesn’t merge in any geometry.

A group of primitives within the object to merge in. Leave this blank to merge in the entire object.

When Group n is not blank, turn this option on to merge in an extra ring of primitives. This is useful for maintaining the correct seam when merging in polygon primitives that are to be subdivided.
