Houdini Python - 10 Copy AOVs - Arnold Part - II

Part - 2 'Functionality'

Brief Thought:

"In this section, we will develop a tool that allows for the transfer of AOVs from the first pass to various selected passes in Arnold within Houdini. The main emphasis will be on integrating this functionality into the user interface."

User Interface:

Details:

1. Here we have chosen several Arnold Passes.

2. All the available AOVs were taken from the First Pass.

3. Next, we forwarded it to the user interface for the user to choose which items to copy from this pass in order to paste them onto all other passes.

Bullet Points for Python Scripts:

• Define Parameters:

Set up variables for accessing AOV parameters like aov_count, aov_label, aov_prefix & aov_enable.

• Get Nodes:

Get selected nodes and careful to only have Arnold node type.

• Bifurcate Nodes:

Decide which node will be the parent and which will be the children.

• Nodes Information:

Message to inform users about the nodes involved.

• Get Parent AOVs Details:

Gets the AOVs count and labels from the parent node.

• User Interface:

Shows a UI for selecting which AOVs to copy.

• Function to process:

If selections are made, processes each AOV to copy from the parent to child nodes.

• Modifying Label:

Adjusts labels of AOVs if their enabled status is False.
