radiance

Professional 32-bit color correction with exposure, contrast, saturation, gamma, and per-channel lift/gain controls.

Professional color grading with per-channel LGG/Offset, cinematic presets, LAB match grading, and JSON grade export.

Match source image color statistics to a reference image using LAB mean/std matching.

Professional HDR tone mapping with presets and advanced controls. GPU-accelerated.

Scene-linear workflow presets. Returns decode/working_space/encode settings for color pipeline.

Composite two images using Normal, Add, Screen, Multiply, Overlay, Soft Light, Difference, or Divide blend modes.

v2.3.3 — Universal cinematic encoder. Auto-selects prose format for Flux/T5/Kolors and structured format for SD1.5/SDXL. Supports scene mood, A/B prompts, subject weighting, real token counts, art direction and architecture-aware negatives.

Compose up to 5 LoRAs into an accumulating LORA_STACK. Chain multiple stacks together. Feed into Radiance Unified Loader.

Generate authentic cinematic prompts using real-world camera and lens profiles.

Universal loader v3.1 — auto-detects architecture (Flux, SD3, SDXL, Wan, LTX 2.3, HunyuanVideo, PixArt, Lumina2, etc.), named CLIP slots, chainable LORA_STACK, model_meta JSON, latent_format, offload mode. ZERO stale cache hits (mtime + size fingerprinting).

AI-powered upscaling using neural network models. Supports tiled processing for large images.

Convert between bit depths with professional dithering to reduce banding.

Generate 360° equirectangular panoramas for HDRI environment mapping in 3D applications.

Professional resolution selector with internal preview card. Outputs empty LATENT for Flux/SDXL/SD with correct channel count. 30+ cinema/social/AI presets. Manual latent_channels override for custom architectures.

Non-destructive debug probe. Logs tensor shape/range/dtype, string values, list/dict lengths. Data is passed through unchanged.

Boolean gate — passes data when open=True, returns fallback (or None) when open=False. Use to enable/disable branches without rewiring.

A/B/C/D input multiplexer — select which of up to 4 inputs to pass through using an index (0=A, 1=B, 2=C, 3=D). Perfect for rapid comparisons without rewiring.

Sticky note for workflow documentation. No data connections — pure display. Supports a title, body text, and color selection.

Lightweight named reroute — label any wire without visual overhead. Backward compatible: the label is optional and purely informational. Use Reroute+ for color, icons, styles and group tags.

Professional labeled reroute — color, icon, style, group tag, description tooltip, and live type introspection. Renders as a styled pill via radiance_layout.js.

Load an image with optional non-destructive mask override. If a companion '_radmask.png' file exists alongside the source image, its alpha channel is used as the mask instead of the image's own alpha. The Radiance mask editor frontend saves masks in this companion format.

Displays any input data as text directly on the node UI.

Reduce inter-frame flicker in video batches via per-pixel EMA with optional motion-aware masking.
