Good day, I have a 15 megabyte babylon file to load, loading the scene from a mobile phone or laptop is pretty slow, is there a way to load in stages or chunks or any other advice to show content to user fast even if load happens incrementally? thank you :slight_smile:

This has now been solved here: [image] onSuccess and onProgress callbacks not working well with incremental loading in terms of tracking completion Bugs You should call it at the end of your first batch slight_smile and all will work as you wish so we can close this o…

Gotta say, if you are going mobile & distributing to other than just yourself, you should learn about Blender’s Limited Dissolve. Reducing your geometry has more benefits than reducing file size. You get it in edit mode off the ‘X’ menu. It only applies to the currently selected vertices, so if t…

@Dad72 David thank you very much, I added the onProgress function and I see that it works, it is returning always 100% so far, I have to test it from mobile to make sure that it returns incremental numbers, because I am using now incremental loading so hopefully will return the intermediate number…

@JCPalmer I just tried the limited dissolve feature in blender, this is really fantastic, thank you very much for recommending it; it really helps to simplify the geometry, stunning really; this is much much better than the decimate modifier. The decimate modifier I could not use, it really destroye…

@JCPalmer , what do you think of this idea in blender duplicate the model, have a high detail version and another duplicated version using limited dissolve that has very little detail then use the incremental loading feature of babylon, so that the low detail version loads first, and then once the …

@JCPalmer yes this is very promising, just tried it and both are loading so now I just have to hide the low detail one once the high detail one has loaded, this is causing me problems because I am trying to access the scene.meshes object inside the onProgress function and its strange, I can see corr…

@Dad72 @JCPalmer This is strange, it seems that the code below, the onProgress function of the incremental loading always has 100% loaded from the beginning and yet never shows length more than 0 of scene.meshes; however the onSuccess function does show all the scene.meshes data correctly; the pro…

I’m wondering if the onProgress function is valid with the incremental system. The scene is loaded as soon as a model is visible, so onSucess is directly called and therefore onProgress is at 100% without having loaded all the objects of the scene. I think that’s the explanation. Maybe @Deltakosh …

@Deltakosh @Dad72 @JCPalmer thank you very much for your help, so to summarize, I am using incremental loading, which is great, definitely I need to use it I am including two versions of the model, one in high detail and one in low detail created with the limited dissolve feature of blender. The h…

@bghgary might have built in tricks for this with GLTF and the MSFT_LOD extension.
