<description>
|
|
MultiMesh provides low level mesh instancing. If the amount of [Mesh] instances needed goes from hundreds to thousands (and most need to be visible at close proximity) creating such a large amount of [MeshInstance] nodes may affect performance by using too much CPU or video memory.
|
|
For this case a MultiMesh becomes very useful, as it can draw thousands of instances with little 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.
