- This material has small built-in lines that divide the glass into panes. Please make sure to set the texture mapping of your skin that uses this glass to be 1 floor in height with an appropriate width like 4' in both the X direction and the Y direction. The easiest way to do this is by creating a box mapping and then using the mapping widget. Scale the mapping widget using Scale1D. Each side of the mapping widget should be the correct/appropriate size.
