Property Descriptions

bool add_uv2 = false

  • void set_add_uv2 ( bool value )

  • bool get_add_uv2 ( )

If set, generates UV2 UV coordinates applying a padding using the uv2_padding setting. UV2 is needed for lightmapping.

AABB custom_aabb = AABB(0, 0, 0, 0, 0, 0)

  • void set_custom_aabb ( AABB value )

  • AABB get_custom_aabb ( )

Overrides the AABB with one defined by user for use with frustum culling. Especially useful to avoid unexpected culling when using a shader to offset vertices.

bool flip_faces = false

  • void set_flip_faces ( bool value )

  • bool get_flip_faces ( )

If set, the order of the vertices in each triangle are reversed resulting in the backside of the mesh being drawn.

This gives the same result as using BaseMaterial3D.CULL_FRONT in BaseMaterial3D.cull_mode.

Material material

The current Material of the primitive mesh.

float uv2_padding = 2.0

  • void set_uv2_padding ( float value )

  • float get_uv2_padding ( )

If add_uv2 is set, specifies the padding in pixels applied along seams of the mesh. If at generation the size of the lightmap texture can't be determined, the UVs are calculated assuming a texture size of 1024x1024.

Array get_mesh_arrays ( ) const

Returns mesh arrays used to constitute surface of Mesh. The result can be passed to ArrayMesh.add_surface_from_arrays to create a new surface. For example:

var c = CylinderMesh.new()
var arr_mesh = ArrayMesh.new()
arr_mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, c.get_mesh_arrays())
