VIEWPORT LIGHT SURFACE STANDARD – OVERVIEW
Viewport Light Surface Standard corrects the default viewport lighting while using Arnold or Surface Standard shaders in Maya 2020+.
Maya’s lights in 2020 now match renderers, but unfortunately appear dark in the viewport.
Arnold and Standard Surface shaders appear darker in Maya 2020 + viewports than in earlier versions; this is an intentional change by Autodesk.
Viewport Light Surface Standard fixes the viewport light by creating a light setup that is callibrated to match Maya’s earlier versions.
The tool instantly creates a directional light with an intensity of 1.7 and parent-constrains it to the current camera.
Quickly rebuild the setup if you change cameras.
