D5 Lite 1.2.0 for Revit: New Features

D5 Lite 1.2.0 for Revit was released for Windows on September 17, 2026. This version introduces CLI for AI Agents (Beta), adds channel output, and updates lighting with Reflection Visibility and full beam angle controls.

Adjust Lite Scenes with External AI Tools

CLI for AI Agents (Beta) lets external AI tools such as D5Arco, Codex, and Claude adjust Lite environment, lighting, materials, cameras, and effects, and render images. The Revit version does not include modeling operations.

1. Keep Revit and D5 Lite open. Follow the connection guide to let your AI Agent find the connection program for the corresponding installation and check its status.
2. Once connected, ask the Agent to read the current scene and available parameters first.
3. Give it a specific adjustment or rendering task, review and confirm the execution plan, then check the result in Lite.

Run the AI Agent under the same Windows user account used to install D5 Lite.

Output Channels with the Main Render

Output channel images alongside the rendered image to select skies, distinguish materials, or work with transparent areas in post-production.

1. Open the render settings and set Output Type to Image.
2. Under Channels, select the channels you need, such as SkyMask, MaterialID, or Transparent.
3. Click Render and choose a save location and file name.
4. Open the output folder when rendering finishes. The channel images appear alongside the main image.

Panoramas and render view screenshots do not output channel images.

Adjust Light Visibility in Reflections

The new Reflection Visibility parameter adjusts how visible a light source is in reflections and refractions while keeping its illumination.

1. Select the Lighting Fixture in Revit and open Light Editor from the D5 Lite toolbar.
2. Adjust Reflection Visibility and compare the light source's appearance on reflective surfaces in the Lite viewport.
3. Keep adjusting until you reach the visibility you need.

To change a light's position or orientation, move or rotate the family instance in Revit.

Reflection Visibility affects the current render. Reopening the Revit project does not restore this setting, so check reflections and adjust it again if needed.

Control Spot Coverage with the Full Beam Angle

Spot Light angles are now shown as the full beam angle, making the coverage easier to judge directly.

1. Select the Lighting Fixture corresponding to the Spot Light in Revit and open Light Editor from the D5 Lite toolbar.
2. Adjust the beam angle and check the light's coverage in the Lite viewport.
3. Save the Revit project to keep the light adjustments written to it.

The beam angle is adjusted independently in Lite and does not continue to follow the native Revit light angle.

Other Improvements

• Camera rotation by dragging is no longer stopped by screen edges.
• Scene thumbnails display the complete scene framing.
• Lite lowers its frame rate when both Lite and Revit are in the background to reduce GPU usage.
• Fixed 90° viewport sync offsets in older saved projects, startup failures with special characters in Windows usernames, and window display issues between monitors with different DPI settings.
