Mesh Merge will combine the scene objects you select into a set of efficient ‘material based’ meshes that can simplify the rendering process.
Since it’s best to render objects with the same material at one time (to avoid having to unload and reload material data), all object meshes with the same material will be merged into a single mesh. In this way, you can select lots of options and Mesh Merge will organize and merge them as needed.
Merge objects with the same materials
Supports objects with multiple materials
Supports objects with sub-meshes
Creates multiple merged meshes in one selection
Manage source objects after the merge
Ability to split objects based on materials
When multiple objects are merged, a separate “Merged Mesh” object will be created for each material in the selected group. All the meshes that use that material are merged into a single mesh. In this way, meshes are assigned to a single material and rendering becomes much more efficient. Below, you can see the effect of selecting 6 objects that use two different materials.
One of the cool side effects of Mesh Merge is that you can use it to split a single object into multiple objects based on the materials used. In this way, you can deconstruct complex objects into simpler ones.
When merging meshes, you typically don’t want to merge every object in the scene into a massive mesh of objects. Instead, merge the objects into groups to take advantage of scene occlusion culling.
