Creating a Colored Glass material
There are two ways to create a colored glass material. The first one can be created by assigning a color to the Transmittance channel. The color will be applied uniformly to the whole model regardless of its thickness. The second option is to make use of the Absorption parameter which controls the color visualized after a distance of 1 meter.
Info: Any absorption value other than zero (0) will force the Transmittance Channel to switch to Absorption Color.
