Decals thickness and following mesh

[artemisia]

decal script is self managed, the trick wrote by gertenko , I see I made mistake in existing script not to put it into ready func.

extends Node3D

static var decals_amount: int = 0
const MAX_DECALS_AMOUNT: int = 10
@onready var decal: Decal = $Decal

func _ready() -> void:
	decals_amount += 1
	if decals_amount > MAX_DECALS_AMOUNT:
		var all_decals := get_tree().get_nodes_in_group("Decals")
		all_decals.pop_at(0).queue_free()
	print(decal.get_cull_mask())
	# cull mask - not 3 "1048571"
	# cull mask - all "1048575"
	# cull mask - not 3 and 5 "1048555"
func _exit_tree() -> void:
	decals_amount -= 1

func _on_timer_timeout() -> void:
	queue_free()

Fireballs - is there way to make burned/smoked area?

Your raycast can get normals. var collider = get_collider() if is_colliding(): var normal := get_collision_normal() but then it seems like you are using remote transforms to copy this positional data instead of moving your _explode function under this if is_colliding() statement if is_colliding(): audio_stream_player_3d.stop() var point := get_collision_point() var normal := get_collision_normal() # get normal var rotate_up := Quaternion(Vector3.UP, normal) # use normal to rotate va…

decal get removed by timer or count higher than 10.

extends Node3D

@onready var animation_player: AnimationPlayer = $AnimationPlayer
@onready var audio_stream_player_3d: AudioStreamPlayer3D = $AudioStreamPlayer3D

func blast() -> void:
	audio_stream_player_3d.play()
	animation_player.play("explosion")
	animation_player.animation_finished.connect(_on_animation_finished)

func _on_animation_finished(_anim_name: StringName) -> void:
	queue_free()

blast get removed by animation finished.
