Question
I am trying to create a VisualShaderNodeCustom in GDScript that exposes a Gradient resource and an Enum dropdown in the Inspector.
The properties in the Inspector consistently display as “Default” with no other enum values. I have tried clearing the cache, restarting the editor, and renaming the class, but the engine seems to fail to bind the PROPERTY_HINT_ENUM metadata to the UI.
How do you correctly register an Enum dropdown for a custom Visual Shader node so the Inspector actually renders the hint_string options?
GDScript
@tool
extends VisualShaderNodeCustom
class_name BlenderRamp
var gradient: Gradient = Gradient.new()
var interpolation: int = 1
func _get_name() -> String:
return "BlenderRamp"
func _get_category() -> String:
return "Custom"
func _get_return_icon_type() -> int:
return PORT_TYPE_VECTOR_3D
# This indexed system is used in VisualShaderNodeCustom
# but consistently results in "Default" labels in the Inspector.
func _get_property_count() -> int:
return 2
