| passName | Shader pass name (case insensitive). |
| enabled | Flag indicating whether this Shader pass should be enabled. |
Enables or disables a Shader pass on a per-Material level.
By default, all Shader passes are enabled. This function allows a Material to treat a specific Shader pass (as indicated by LightMode pass tag)
as if it does not exist in the Shader. For example, if the Shader has a "refraction" pass but you only want to enable it on Materials that have
a refraction Texture assigned, pass "refraction" as passName and false for enabled for Materials without a refraction Texture assigned.
Note that the Shader pass enable/disable flag only affects custom rendering pipelines that use the RenderLoop class (via RenderLoop.DrawRenderers or RenderLoop.DrawShadows).
