Question
I’m creating camera and a directional light via gdscript.. but I never get any shadow effect and looks like everything just stays on full bright all the time. Now if I build this same scene in the editor he lighting is proper.
My code:
func CreateDirectionalLight(node):
var new_light_3d = DirectionalLight3D.new()
node.add_child(new_light_3d)
new_light_3d.name = "Directional Light"
# Basic setup
new_light_3d.light_energy = 1.5 # Brightness
new_light_3d.light_color = Color(1, 1, 1) # White light
new_light_3d.shadow_enabled = true # Enable shadows
# Orient the light (pointing down at an angle)
new_light_3d.rotation_degrees = Vector3(45, 0, 0)
return new_light_3d
func CreateCamera(node):
var new_camera_3d = Camera3D.new()
node.add_child(new_camera_3d)
new_camera_3d.name = "Camera"
return new_camera_3d
Whats wrong ?
This would be pointing up at an angle, try -45?
Yah I tried that before posting, was just trying different things.
Ok to reproduce this, I made a new scene. Added a 3d Scene Node to it. then attached this script.
func _ready():
# --- Directional Light ---
var light = DirectionalLight3D.new()
light.rotation_degrees = Vector3(-45, -45, 0)
node.add_child(light)
# --- Plane (Ground) ---
var plane_mesh = MeshInstance3D.new()
plane_mesh.mesh = PlaneMesh.new()
plane_mesh.scale = Vector3(10, 1, 10) # make it larger
# Add material (green ground)
var plane_material = StandardMaterial3D.new()
plane_material.albedo_color = Color(0.2, 0.8, 0.2) # green
plane_mesh.material_override = plane_material
node.add_child(plane_mesh)
# --- Cube ---
var cube_mesh = MeshInstance3D.new()
cube_mesh.mesh = BoxMesh.new()
cube_mesh.transform.origin = Vector3(0, 1, 0) # above the plane
# Add material (blue cube)
var cube_material = StandardMaterial3D.new()
cube_material.albedo_color = Color(0.2, 0.4, 1.0) # blue
cube_mesh.material_override = cube_material
node.add_child(cube_mesh)
# --- Camera ---
camera = Camera3D.new()
camera.transform.origin = Vector3(5, 5, 10)
camera.look_at(Vector3(0, 1, 0), Vector3.UP)
node.add_child(camera)
As you can see there is no lights or shading at all in this scene.
With this script you omitted enabling shadows
# --- Directional Light ---
var light = DirectionalLight3D.new()
light.rotation_degrees = Vector3(-45, -45, 0)
light.shadow_enabled = true
node.add_child(light)
With this change I see the cube’s shadow.
