Working with Large Number of Objects
When the virtual scene contains a large number of objects, both identical and unique, managing each of them is a very complicated task. Moreover, when such objects are represented in the scene as separate meshes, the performance significantly drops.
UNIGINE allows managing a great number of objects as a single object by using clusters and clutters. It simplifies a spatial tree of nodes (in the World Hierarchy, there will be one or several objects instead of thousands), thus increasing the performance.
- Mesh Cluster and Mesh Clutter nodes allow managing a great number of identical meshes (or nodes in case of a World Clutter) in the world.
- World Clutter nodes allow managing a great number of node references in the world.
Clusters allow you to manage a lot of objects as a single object, while keeping the ability to independently edit each mesh baked in the cluster.
Mesh Cluster contains only identical meshes. So, if you need to create a complex construction that contains several types of identical meshes (like the tube construction on the picture below), you will have to bake several mesh clusters:

The detailed instructions on baking meshes/nodes to the cluster can be found in the corresponding articles referenced above, as well as in the Content Optimization video tutorial.
Clutters are almost the same objects as clusters. The main difference is that the clutter scatters objects randomly and doesn't allow editing each object baked into the clutter individually. However, such peculiarity makes the clutter objects more preferable from the perspective of the performance.
There are 2 types of clutters:
- Mesh Clutter contains only identical meshes randomly scattered across the area.
- World Clutter contains randomly scattered node references. It means that you can bake different objects into the clutter and randomly position them.
