Is it at all possible to combine the child meshes/materials of a GameObject in the editor, rather than at runtime? I'd like to assemble level design "building blocks" into things like rooms and hallways, and then combine them into prefabs.
Hi!
If it is an option, you can use the Easy Mesh Combiner tool. It can combine your meshes quickly and very easily, 100% through the editor. It’s a wonder to combine the meshes of the scenery and even get more performance! You simply select which GameObjects or children that should have the meshes combined, right-click and combine everything!
Worth a try. Here is the tool link (Available in the Asset Store)
