<?xml version="1.0" encoding="UTF-8" ?> <class name="MeshInstance3D" inherits="GeometryInstance3D" version="4.0"> <brief_description> Node that instances meshes into a scenario. </brief_description> <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 reuse of geometry which can save on resources. When a [Mesh] has to be instanced more than thousands of times at close proximity, consider using a [MultiMesh] in a [MultiMeshInstance3D] instead. </description> <tutorials> </tutorials> <methods> <method name="create_convex_collision"> <return type="void"> </return> <description> This helper creates a [StaticBody3D] child node with a [ConvexPolygonShape3D] collision shape calculated from the mesh geometry.
