Set the default Variable Rate Shading (VRS) mode for the main viewport. See [member Viewport.vrs_mode] to change this at runtime, and [enum Viewport.VRSMode] for possible values.

If [member rendering/vrs/mode] is set to texture, this is the path to default texture loaded as the VRS image.

The texture [i]must[/i] use a lossless compression format so that colors can be matched precisely. The following VRS densities are mapped to various colors, with brighter colors representing a lower level of shading precision:
