Camera Bake HDA Description
Overview
The Camera Bake HDA is a utility tool for Houdini that creates a baked version of an existing camera with keyframes at every frame. It converts dynamic/procedural cameras into static keyframed cameras while preserving the same visual output.
Purpose
Convert procedural or dynamically controlled cameras into keyframed cameras
Create camera exports compatible with other software applications
Generate simplified camera representations for rendering optimization
Preserve camera movement and parameters without dependencies on the original setup
Parameters
Source Camera: Input camera to be baked
Frame Range: Start and end frames for the baking process
Bake Transform: When enabled, bakes position and rotation (tx, ty, tz, rx, ry, rz)
Bake Camera Parameters: When enabled, bakes camera-specific parameters (focal length, aperture, near/far clipping, resolution, etc.)
Usage
Select a source camera node
Define the frame range for baking
Choose which parameter groups to bake (transform, camera parameters, or both)
Execute the HDA to create a new camera with the suffix “_bake”
Technical Notes
Creates a new camera node rather than modifying the original
Sets keyframes at every frame in the specified range
Validates inputs (camera type, frame range, parameter selection)
Copies both transform data and camera-specific parameters as specified
This tool is particularly useful for pipeline integration, rendering optimization, and ensuring camera stability across different Houdini sessions or when exporting to external applications.
