Auto Rim Light

What it is

A versatile, node-based shader that reacts to the position of an Empty. Move, rotate, or scale the Empty and watch the rim light glide around your model—no extra lights or messy constraints required.

Why you’ll love it

• Pin-point control – Light just one hero product in a crowded scene or give every asset its own dramatic edge.
• Instant product-photo polish – Rim light separation without the studio setup.
• Animation-ready – Keyframe the Empty for dynamic reveals or stylised motion-graphics glows.
• Fully editable –
  • Tweak the ColorRamp to soften or sharpen the fall-off.
  • Push the Layer Weight slider if you need a bolder halo.
• Zero add-ons – 100 % native Blender shader; drag-and-drop into any file.

2. Add the supplied Empty (or any Empty you like).
3. Select the material → “Object” input → pick your Empty.
4. Move the Empty around—done!
