Drawing thousands of [MeshInstance3D] nodes can be slow, since each object is submitted to the GPU then drawn individually. MultiMesh is much faster as it can draw thousands of instances with a single draw call, resulting in less API overhead. As a drawback, if the instances are too far away of each other, performance may be reduced as every single instance will always rendered (they are spatially indexed as one, for the whole object). Since instances may have any behavior, the AABB used for visibility must be provided by the user. </description> <tutorials> - <link>http://docs.godotengine.org/en/latest/tutorials/3d/vertex_animation/animating_thousands_of_fish.html</link> + <link>https://docs.godotengine.org/en/latest/tutorials/3d/vertex_animation/animating_thousands_of_fish.html</link> + <link>https://docs.godotengine.org/en/latest/tutorials/optimization/using_multimesh.html</link> </tutorials> <methods> <method name="get_aabb" qualifiers="const"> @@ -56,17 +57,6 @@ Returns the [Transform2D] of a specific instance. </description> </method> - <method name="set_as_bulk_array"> - <return type="void"> - </return> - <argument index="0" name="array" type="PoolRealArray"> - </argument> - <description> - Sets all data related to the instances in one go.
