The Pixel Shader plug-ins are part of the PixelFX plug-ins set.
Viz Artist does not support more than one general shader on a Container, or in a nested fashion. However, in some cases, PixelFX, by its nature, does support multiple shaders per Container.
Some have high cautionary indications. Some are very light. Some are stackable, and others are not.
The following Shader plug-ins are located in the PixelFX folder:
Most of the plug-in icons have mini icons that show certain properties of the particular plug-in:
At the bottom left, there is a performance bar, with three blocks (like a cellphone battery indicator). One block means the plug-in does not have a drastic performance effect, and three means the plug-in is taxing and should therefore be used with caution.
At the bottom right, the orange stack shows if the plug-in is stackable, meaning it can be used in conjunction with color correction plug-ins.
Some plug-in icons themselves are divided in half with one side showing the visual effect with the plug-in and the other without it.
