Oh sorry! I do the acronym thing too often! Hierarchical Instanced Static Meshes is basically just instanced static meshes, but with the added bonus of being able to have controlled LODs. HISMs are massively more performant than normal static meshes. Since you were handling this under one BP before, this won’t be much of a change. The only downside of these things is that these instances have to be one specific mesh. However, nothing is stopping you from having multiple sets of these instances. This won’t work for all use cases, but if enough of your objects are similar or the same mesh, this can help immensely!
