Glass transparent shaders are used for environmental and model glass surfaces. This shader type is characterized by its various reflectivity and tint settings which let you control how the glass appears from different angles and how light passes through it.

Known issues

In Custom Edition, glass shaders which use bump-mapped reflections render incorrectly. Instead of using the intended reflection cube map, the renderer uses the vector normalization bitmap from globals, causing reflections to be brightly multicoloured. This issue is fixed in H1A.

Function/global

Type

(rasterizer_active_camouflage_multipass [boolean])

Toggles whether or not transparent shaders are shown through active camouflage. If disabled, shaders like glass or lights will not be visible through a camouflaged unit.

Global
(rasterizer_model_transparents [boolean])

Toggles the rendering of transparent shaders in models. For example, the Warthog's windshield.
