Dive-in:

macbeth_refSphere_setup (Geometry Node)

The primary goal of establishing boundaries for the Reference Macbeth and Spheres has been successfully met. This process involved clearly outlining the crucial elements for positioning and structuring the setup within the camera view. Furthermore, a range of toggle functions has been integrated, allowing users to easily switch on or off the spheres and the chart for enhanced flexibility and customization.

matnet (Material Network)

All materials related to HDA have been generated and the setup has been completed in this location.

ropnet (Render Operator Network)

The Render Pass is combined with the camera settings, resolution, renderable objects, and lights in this process. Additionally, Arbitrary Output Variables (AOVs) are included to aid in the clear visualization of materials.

Ground (Geometry Node)

The grid has been set up with shadow material, and a switch has been added to turn the ground on and off.
