Sets the active environment blend mode.
[param mode] is the [enum XRInterface.EnvironmentBlendMode] starting with the next frame.
[b]Note:[/b] Not all runtimes support all environment blend modes, so it is important to check this at startup. For example:
[codeblock]
func _ready():
var xr_interface : XRInterface = XRServer.find_interface("OpenXR")
if xr_interface and xr_interface.is_initialized():
var vp : Viewport = get_viewport()
vp.use_xr = true
var acceptable_modes = [ XRInterface.XR_ENV_BLEND_MODE_OPAQUE, XRInterface.XR_ENV_BLEND_MODE_ADDITIVE ]
var modes = xr_interface.get_supported_environment_blend_modes()
for mode in acceptable_modes:
if mode in modes:
xr_interface.set_environment_blend_mode(mode)
break

Opaque blend mode. This is typically used for VR devices.

Additive blend mode. This is typically used for AR devices or VR devices with passthrough.

<constant name="XR_ENV_BLEND_MODE_ALPHA_BLEND" value="2" enum="EnvironmentBlendMode">
Alpha blend mode. This is typically used for AR or VR devices with passthrough capabilities. The alpha channel controls how much of the passthrough is visible. Alpha of 0.0 means the passthrough is visible and this pixel works in ADDITIVE mode. Alpha of 1.0 means that the passthrough is not visible and this pixel works in OPAQUE mode.
