MeshInstance3D

Node that instances meshes into a scenario.

Description

MeshInstance3D is a node that takes a Mesh resource and adds it to the current scenario by creating an instance of it. This is the class most often used render 3D geometry and can be used to instance a single Mesh in many places. This allows reusing geometry, which can save on resources. When a Mesh has to be instantiated more than thousands of times at close proximity, consider using a MultiMesh in a MultiMeshInstance3D instead.

Property Descriptions

Mesh mesh

  • void set_mesh ( Mesh value )

  • Mesh get_mesh ( )

The Mesh resource for the instance.

NodePath skeleton = NodePath("..")

NodePath to the Skeleton3D associated with the instance.

Skin skin

  • void set_skin ( Skin value )

  • Skin get_skin ( )

The Skin to be used by this instance.

Method Descriptions

void create_convex_collision ( bool clean=true, bool simplify=false )

This helper creates a StaticBody3D child node with a ConvexPolygonShape3D collision shape calculated from the mesh geometry. It's mainly used for testing.

If clean is true (default), duplicate and interior vertices are removed automatically. You can set it to false to make the process faster if not needed.

If simplify is true, the geometry can be further simplified to reduce the number of vertices. Disabled by default.
