Houdini 22.0 Nodes Copernicus nodes

Block Begin Copernicus node

Start of a block, containing its inputs.

This node is the beginning of a block. You can use blocks to encapsulate a function that can be executed either inline by plugging inputs into the Block Begin COP or externally by using the Invoke Block COP. Slap comp programs are also authored using blocks.

You can specify inputs to the block on this node.

Note

In Copernicus blocks, you can’t use Time Shifts when they require the inputs of the block to cook at different times. As a workaround, Time Pack the required frames before the Block Begin and wire them into the block as a cable. Each iteration of the block extracts only the required wire from the cable.

Parameters

Block Path

The path to the Block End COP that’s the final and closing node of this block. The Block End node must be at the same network level as this Block Begin node.

Rename Wires Using Output Labels

When this toggle is enabled, name of each output wire is set based on its respective port label. Otherwise, wire names are propagated from inputs. Turn this option on if you'd like to discard incoming wire names and harden new ones for the downstream network to use.

Block Inputs

The number of inputs to this block.

Input Name

The name of the input. This string identifies the input when using the Invoke Block COP to execute the block, or when binding inputs for slap comp.

Input Type

The type of the input. This controls what kind of data can be fed into the corresponding port (or bound to the input), as well as what the input can be plugged into.

See Data types for more information.
