- Implemented the "O Image Relief Plane" Geometry Nodes group to create a fixed-base image relief using depth images and various parameters. - Created the "O Shadeless" shader node group to display color without scene lighting while preserving shadows and reflections. - Introduced a preview feature for node groups, allowing for interactive visualization of node arrangements in an HTML format. - Added a template HTML file for rendering node previews with customizable views and controls.
