Not working with other blender models

[ghost]

Hi @hemanthrajv
The example works out of the box if I update the gradle version to latest.

I am facing issues with loading a different model. I tried a couple of models and am getting the error

E/flutter (31925): [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: Unable to load asset: assets/BodyMesh.obj

Thank you again for sharing your awesome work.

PFA the file I am trying to use. Hope this helps. Please do let me know if there is some specific format that must be used to export the .obj file.

Thanks again.

Hi, thanks for writing to me. The library merely renders 3D object from .obj file.

Your body mesh does work perfect without any issues.

Here is the screenshot of your model

Things you can check:

• See if you've added the .obj file to assets correctly
• Check if assets are specified properly in your pubspec.yaml
• Ensure the asset name is correctly give to the Object3D class

Hope this helps!

Closing the issue as it is not plugin related.

Feel free to get back if the above methods did not help!

Hi @hemanthrajv
Can you let me know the platform you are using to test this ? If using an emulator, please let me know if tihs works on a real device.

The code compiles fine and I am getting run time error as mentioned above. Here is the exact info I get from my terminal.

I think this may be a run time issue related to my mobile. I am uisng Samsung Galaxy S8.

Let me know if you can help me with this.

Hi @hemanthrajv
I renamed the file to abodymesh.obj and it works ok now. Maybe something to do with file name.

How can I add texture to this models ?
Also is there a way to pinch zoom ?
