This function takes the current texture as an environment map and shows it as Reflection at the selected heightmap.

This heightmap is either given by the Source Texture, like seen in Image 2, or by the Mask, which displays Image 3.

Increase the Pre-Smoothing value to get smoother reflections.

The height of the heightmap can be regulated with the Amplify value. Parallel to this value, the strength of distortion increases.

The environment map is projected onto a sphere. With the Tiling values you can control the repetition of the texture on this sphere.
