I’m building a small POC game, and I’m looking at the loader, but I can only find methods that immediately add the loaded obj to the scene. How can I “preload” an obj file and then use the loaded data to create multiple objects with the same model during the game?

Here’s some code from a game I have that loads a few dozen meshes, hides them all, and then I make instances of those meshes when players spawn later. I skipped a lot but I hope it can still be useful. I was using assetsManager, here’s the link: ( Babylon.js Documentation ) const Atlas = { gunMes…

One thing you might do is actually fully load it, but disable it. This way the shader will already be compiled. When you enable it, it will not have a frame studder. I understand that you might think just downloading in advance might give better initial load time, but coming in the very near future…

For the multiples part of your question, Once you have a mesh, you can create either instances or clones. Clones share geometry, but can have different materials. They require a separate draw call. If you share the same material, you can make an instance. These draw in the same call on most har…

You can take a look at this post as I guess you are looking for the AssetContainer: [image] Will Assets Manager keep similar loaded meshes between scenes? You could also use an Asset Container to store elements outside of a scene: Babylon.js Documentation

@JCPalmer Thanks for the great explanation, it helped me understand a bit more what’s going on (wrt compiling the shaders and clones vs instances). I think having my meshes fully loaded and ready to go would be ideal. I just don’t need a lot of them at the start of the game but they do need to spaw…

So I’ve been trying to implement the AssetContainer, but it only has addAllToScene(). So how would I go about having a “root” mesh not in the scene and then create instances of it in my scene?

you can get your mesh from assetsContainer.meshes

I got that, but how do I add an instance of the mesh to my scene, without adding the original mesh as well?

you should just be able to clone it

Do you have an example of how to do this? Cause I don’t seem to be able to get it working. What I’m trying to do: const container = await SceneLoader.LoadAssetContainerAsync('res://', 'filename.obj'); container.createRootMesh(); function get() : InstancedMesh { const rootMesh = container.mesh…

You cannot clone an instance. Either you clone or you instanciate a mesh buy you cannot do both Sonin your case I would call assets container[0].createInstance() or .clone()
