God Rays

​

What this node does

God Rays creates streaks of light that fan out from a source position by repeatedly scaling and fading a bright version of the frame toward that point. It produces the classic “shafts of light” look — sunbeams, divine light, a bright doorway. This is a rendered stage — it needs a ▶ Run. It uses a torch (GPU) backend. In goes COMFYTV_VIDEO, out comes COMFYTV_VIDEO. To hand the result to a native ComfyUI node, insert a Bridge. See bridges.md.

​

When to use it

• Add sunbeams through trees, clouds, or a window.
• Give a bright light source a dramatic, volumetric glow.
• Sell an atmospheric, hazy, or heavenly mood.

​

Parameters

​

translate_x / translate_y

Each -2000.0–2000.0 (step 1.0), default 0.0. Position of the light source that the rays radiate from, offset in pixels from center. Move these to place the “sun”.

​

scale

0.2–4.0, default 1.4. How far each ray step reaches — larger values give longer, more spread-out shafts.

​

rotate_deg

-180.0–180.0 (step 0.5), default 0.0. Rotation of the ray direction, in degrees (positive is counter-clockwise).

​

steps

1–7, default 5. Number of radial sampling steps used to build the shafts. More steps = smoother, longer rays (and more compute).

​

decay

0.001–1.0, default 0.3. How quickly the rays fade with distance from the source. Lower = shorter rays; higher = longer, brighter rays.

​

max_mode

Boolean, default false. When on, the rays are combined using a max (lighten) operation rather than the default additive blend — useful to keep highlights from clipping.

​

mix

0.0–1.0, default 1.0. Blend of the rays over the original frame. Lower to make the effect subtler.

Tips

• Set translate_x/translate_y so the source sits on your actual light (a window, the sun) for a believable result.
• Combine with Glow for a bloom around the source plus radiating shafts.
