Houdini 21.0 Nodes Copernicus nodes

SOP Invoke Graph Copernicus node

Invokes a geometry SOP graph on the inputs.

On this page
Since 21.0

This node runs a geometry SOP graph on the inputs. The node arranges the incoming COP inputs into geometry that it assigns to the inputs of the geometry graph.

This node is useful in special use cases.

Note

Geometry graphs can’t contain expressions or channels, so it’s not often a simple conversion from a node network to a geometry graph. Use parameter overrides to gain the functionality of channels.

Parameters

Input Group

The ordered point group that specifies which nodes in the geometry graph to use as inputs.

Inputs

The number of inputs for the geometry graph.

Output Group

The ordered point group that specifies which nodes in the geometry graph are outputs.

Outputs

The number of outputs from the geometry graph.

Unload Behavior

Whether to unload the executed block’s intermediate data or cache it on this node. Since compiled blocks are usually used for repeated sections that shouldn’t cache, the default is Always (which uses less memory).

Never

Cache the executed block’s intermediate data.

Use Node’s Flag

Check this node’s Unload flag to determine whether to unload the cache.

Always

Always unload the intermediate data (don’t cache).

Inputs

graph

A geometry graph, which is often generated from the Attribute from Parameters SOP, that defines the block to invoke.

input#

The geometry to provide to the corresponding input of the compiled SOP block. The amount of node inputs and their details are based on the Inputs information.

Outputs

output#

The result of the geometry graph. The amount of node outputs and their details are based on the Outputs information.
