Question Load 3D Model from Cloud and use it as AR model.

My Problem:
in my Applikation I have a dynamic list of models based on the available Prefabs which should be updated from an existing cloud storage. I want to add new 3D models in this online storage without having to create a new version of my Unity App.
Simplified:
What i have to do now:
Add 3D Model to Assets/Models -> generate a Prefab of the Model -> rebuild my Applikation -> use new Model in App

What i want to do:
upload 3D Model to Cloudstorage -> use new Model in App

Is this possible?

 

Hi @AbayErol,

Of course, it's possible. Use GLTF format for 3D models.
Then, you can import them using this plugin at runtime.

Good luck!

 

Thank you i will try it as soon as possible!

 

adding few other alternatives:
- could use asset bundles (but bundles need to be created in unity editor though) https://docs.unity3d.com/Manual/AssetBundlesIntro.html
- there's also many other runtime import formats, obj, fbx and more (can find free ones in github and paid solutions in asset store)

 

Hi and sry for late response i had some troubles
Ok i tried
https://github.com/Siccity/GLTFUtility
https://github.com/atteneder/glTFast

With those librarys i could sucessfully instantiate from the Cloudstorage
but some Models couldn´t be imported/converted.

My Applikation should run on IOS and Android.

The GLTFUtility library works fine in the editor but on my Phone the crash due to memory Problem. It seems the app want to allocate to much memory in the Heap but i am not sure.

The GLTFast Library had the same Problem but the app didn´t crash.

Do you have experience using gltf importer for mobile devices?

Currently I take a closer look at the File itself maybe the gltf exporter did a bad job :/

The Problem with asset Bundles is that i need to run a server that converts incomming uploads to usable asset Bundles but maybe this is the only solution I don´t know.

 

Hi, did you solve it? I have the same problem. I want to download the file and use it in AR as an object.

 

It's very easy to do this using asset bundles.

I have an old example where I did exactly that, you can see how I did it. https://github.com/tomicz/project-bundle-download-ar

Also I am craeting a framework that helps AR developers to do multiple things, you can watch/star/follow my project https://github.com/tomicz/unity-tomicz-ar-framework It's still in early development (not recommended for production), so you will have to wait, but I will add it ASAP.

 

Yes, but I mean that I want to download objects from the cloud without touching unity. Eg. if I add a gameobject in the cloud I want that unity read it automatically.

 

Then do what @ibrahimpenekli told you above. I never did it myself but I know developers who used that format to accomplish exactly what you are looking for.
