The default colors of SmoothTerrain are rendered around Terrain Materials when their colors are changed.
Discovered this when I went to test SmoothTerrain on mobile, thought it was directly linked to mobile. Turns out it’s linked to the graphics settings.
When you adjust your graphics settings to any number under 7 the bug occurs, as shown in the video below.

You should be able to recreate this in any game that doesn’t use the default Terrain Material colors.
Mobile vs PC Examples
In the following examples, the Glacier material’s Color3 value has been changed to [116, 74, 63] from it’s original [101, 176, 234]. This bug is obvious even with less dramatic changes to color, as shown in the Extra Examples below.
