Sets the update mode for Variable Rate Shading (VRS) for the viewport. VRS requires the input texture to be converted to the format usable by the VRS method supported by the hardware. The update mode defines how often this happens. If the GPU does not support VRS, or VRS is not enabled, this property is ignored.
|
||||||
|
If set to [constant RenderingServer.VIEWPORT_VRS_UPDATE_ONCE], the input texture is copied once and the mode is changed to [constant RenderingServer.VIEWPORT_VRS_UPDATE_DISABLED].

Generates the VRS texture based on a render [param target_size] adjusted by our VRS tile size. For each eyes focal point passed in [param eye_foci] a layer is created. Focal point should be in NDC.
|
||||||
|
The result will be cached, requesting a VRS texture with unchanged parameters and settings will return the cached RID.
