Native 32-Bit Scene-Linear Engine
Unlike standard ComfyUI nodes that clamp to 8-bit, Radiance preserves full IEEE 754 floating-point precision across the entire chain. Zero banding. Zero data loss.
- Smart Overwrite Protection —
Radiance WriteandEXR Savenow feature automated index detection to prevent accidental file destruction. - Universal Digital Cinema I/O — Consolidated Video, Image Sequence, and Single Image handling into a high-performance unified pipeline.
- Robust Pipeline Validation — Enhanced null-safety and input checking for high-load production environments.
- Terminal HUD & Live REPL — Nuke-style Python interaction directly inside the viewer for real-time data inspection.
- Interactive Mask Editor — Non-destructive brush masking in
◎ Radiance Load Image. - ◎ Radiance Grade Match — Shot-to-shot color statistics transfer using CIE L*a*b* mean/std math.
The Radiance Workspace node is the command center for your production. It handles project paths, versioning, and state management, ensuring that all 32-bit data is tracked correctly across your workflow.
- Add the Workspace Node: Right-click > Radiance > Project > Radiance Workspace.
- Set your Project Path: Point it to your production directory.
- Connect to Viewer: Link the
workspaceoutput to the Radiance Viewer to enable live telemetry and Python REPL.
The suite is organized into 11 specialized production zones to mirror industry-standard VFX software topology.
