Light Blocker Transform | Houdini/Arnold | HDA

A more user-friendly Light Blocker for Houdini and Arnold. You can easily transform your Light Blocker in the viewport while rendering. All the parameters are from the main Light Blocker.

Two main features:

1) Gizmo - A geometry gizmo to visualize the blocker region in the viewport.

2) Transform - easy to transform in the viewport or type out exact values.

Script:

You can save this script on the shelf.

select Arnold Light/s and run the script, it will generate a Light Blocker per light,

and automatically assign OUT_light in the respective light's light_filter

if you select nothing and run the script, it will still generate a Light Blocker,

which you can manually plug in Arnold Light
