BlinkScript based node that produces reflections from a world normals aov and an environment map.
The node is designed to work with an equirectangular enviorment map with a aspect ratio of 2:1
The mapped environment can be rotated along a 3D axis and a 2D offset.
A facing ratio mask can be enabled to produce a more realistic effect. To produce this effect a camera is required to work properly.
The output can be premultiplied given that an alpha channel is available with the normals aov. The multiply knob controls the the output rgb luminance values.
You can find here a breakdown of the node with examples: LINK
Here is the source code of the node: LINK
