While using Oculus Quest 2 controllers, ControllerModelLoader says "Unable to load model animation."

[s871922003]

Hello, I was trying to run the HandInteractionExample scene with Oculus Quest 2, but something went wrong and ControllerModelLoader.cs throw out an error log that says "Unable to load model animation".

This results in a visual mode that despite having the correct shape of the Quest 2 controllers but the whole thing only has bright pink color on it.

The logs I get from running HandInteractionExample scene are as followed:

Following up on this one, I found that the model can be correctly displayed in the HandInteractionExample scene (with no animation still, but the visual is correct), but will have that pink appearance I mentioned in the SampleEmptyMRTKScene

The logs I get from running SampleEmptyMRTKScene are as followed:

Can someone kindly teach me how to solve this issue?

Also there's still no controller visual for Vive Focus 3 ?
A fallback model is being loaded when I run the scene on Vive Focus 3. Currently, I replace the fallback model with the one I found in Wave SDK but I wonder if this is the right way to do it?

For the pink textures, do you have both the glTFast package and its KTX extension installed? https://github.com/atteneder/KtxUnity

For the animations, that's currently by-design. Meta implemented their controller model animations differently than MSFT, and MRTK3 doesn't currently support that implementation.

Hi keveleigh,
Thanks for replying~ I actually have both gITFast and KTX extension installed in project, the strange thing is pink textures does not happens in HandInteractionSample scene so that scene must have something to handle the controller texture right?

And for the animations, sorry my native language is not english but do you mean if I want animation for the controllers I needed to let Oculus SDK to handle this part rather than MRTK3?
