[Solved]TriLib on Hololens, folder access

I'm trying to use https://assetstore.unity.com/packages/tools/modeling/trilib-model-loader-package-91777 to load models at runtime. The idea is to have a json file containing the file names and additional info and the models as fbx.

Ideally I want to use a folder that is visible when you connect the hololens to a PC via USB. So I am trying to the "3D Objects" folder. My app has permission to access that folder, I can load the json file just fine. Now when I try to load a fbx file with TriLib the Assimp part in there returns a "Unable to open file". When I put the fbx in ApplicationData.Current.LocalFolder TriLib can access and load it. The problem is that would require the user to use the device portal or for me to implement some upload function in the app.

Has anyone run into this kind of problem and know how to fix it?

 

Ok workaround, use File.Copy to copy the file to the LocalApp folder and then TriLib can access it.

Hi Roest I am using this asset as well.. when I load a model using the asset loader example how can I apply the box collider/near interaction grabbable and handler prefabs to the object ? Do I have to add it manually each time the model loads ?

 

You can use a predefined prefab with all scripts you need like a container. Just check if some of the scripts need to reattach to the newly loaded object.

 

Hello, could you please post the code you used on how to use Trilib to load an fbx file on HoloLens?
