Hi, I’m new to UV mapping and I’m having some problems.
I made a SpatialMaterial with a 16x16 texture that has drown an arrow. I’m trying to put that texture in all faces of a cube, but the cube is one color only. I show you my code.
First, the singleton VoxelData.gdthat contains information about the indices and faces:
extends Node
const voxelVertices : Array = [
Vector3(0,0,0),
Vector3(1,0,0),
Vector3(1,1,0),
Vector3(0,1,0),
Vector3(0,0,1),
Vector3(1,0,1),
Vector3(1,1,1),
Vector3(0,1,1)
]
const voxelFaces : Array = [
[3, 0, 1, 1, 2, 3], # back face
[6, 5, 4, 4, 7, 6], # front face
[7, 3, 2, 2, 6, 7], # top face
[0, 4, 5, 5, 1, 0], # bottom face
[7, 4, 0, 0, 3, 7], # left face
[2, 1, 5, 5, 6, 2] # right face
]
const voxelUVs : Array = [
Vector2(0,1),
Vector2(0,0),
Vector2(1,0),
Vector2(1,0),
Vector2(1,1),
Vector2(0,1)
]
Now the script that creates the cube and adds it to the world:
extends Spatial
func _init():
var voxel = simpleVoxel.new()
add_child(voxel)
class simpleVoxel extends Spatial:
func _init():
var surfaceTool : SurfaceTool = SurfaceTool.new()
surfaceTool.begin(Mesh.PRIMITIVE_TRIANGLES)
for i in range(VoxelData.voxelFaces.size()):
for j in range(6):
surfaceTool.add_vertex(VoxelData.voxelVertices[VoxelData.voxelFaces[i][j]])
surfaceTool.add_uv(VoxelData.voxelUVs[j])
surfaceTool.generate_normals()
var meshInstance : MeshInstance = MeshInstance.new()
var mesh : Mesh = surfaceTool.commit()
meshInstance.mesh = mesh
var spatialMaterial : SpatialMaterial = preload("res://Materials/SimpleMaterial.tres")
spatialMaterial.params_cull_mode = spatialMaterial.CULL_BACK
meshInstance.material_override = spatialMaterial
self.add_child(meshInstance)
