# D5 Lite 1.2.0 for Rhino: New Features

D5 Lite 1.2.0 for Rhino was released for Windows on September 17, 2026. This version adds external AI Agent connections and channel output, with improvements to camera rotation, scene thumbnails, and background GPU usage.

## Adjust Lite Scenes Through External AI Tools {#ai-agents}

CLI for AI Agents (Beta) lets external AI tools read the Lite scene and adjust environment, lighting, materials, camera, and effects, or render images. The Rhino version does not include the modeling operations available in the SketchUp version.

1. Install and open Rhino and D5 Lite under the same Windows user.
2. Follow the connection guide and have your AI Agent check the Lite connection program for the current Rhino installation and the host connection status.
3. Once connected, ask the Agent to read the scene and identify the parameters available for adjustment.
4. Describe an adjustment or rendering task, review the Agent's execution plan, confirm it, and check the result in Lite.

The installer includes the connection program. To keep scene adjustments after execution, update the corresponding scene and save the `.3dm` file.

## Output Channels Alongside the Main Image {#channels}

Channel images help you make selections or composite in post-production. For example, use SkyMask to select the background or MaterialID to distinguish material areas.

1. Open render settings and set Output Type to Image.
2. Under Aspect Ratio, select the channels you need in Channels: SkyMask, MaterialID, Reflection, or Transparent. You can also select all channels.
3. Choose the image quality and format, click Render, and select a save location and filename.
4. When rendering finishes, find the channel images in the main image's folder, with the channel name appended to each filename.

Panoramas and render view screenshots do not output channels. If no channels are selected, only the main image is rendered.

## Camera, Scene, and Background Improvements {#workflow-improvements}

- Camera rotation no longer stops at the screen edge, making continuous inspection easier.
- Scene thumbnails show the complete scene frame to help identify compositions.
- Frame rate drops automatically when both Lite and Rhino are in the background, reducing GPU usage.
