I want to load point clouds, urban white models, 3D tiles and other resources in the scene; Are there any good methods or related tutorials?
Have you tried our doc page? https://doc.babylonjs.com ? This is where we keep everything we know about the framework
When it comes to different inputs, we support many file types. Otherwise you can create a custom loader or generate a mesh using the data you have. but without examples or a playground where you show wat you are trying to do it is very hard to help.
