New day, new update. The max opacity for the reflection layer has been increased (0.025 > 0.100) and now you can change the color of the reflection. That's about it, really. Compatible with Blender versions 2.x, 3.x and 4.x.
Suitable for use with both the Cycles & Eevee rendering engines. Free to use, edit or modify this .blend file. No credit required, but would be great if you do.
