Hardware

Oculus 6Dof device

Steps to Reproduce

1. Open FxR, it will disappear one of controllers intermittently.

Current Behavior

One of controllers will disappear intermittently.

Expected Behavior

We should see both controllers, unless there is only one controller be turned on.

Possible Solution

I would guess this is an asyn problem of the model or image loader when using multiple controllers.

Context

Error Logs and Stack Traces

[daoshengmu]

I notice the controller models are loaded properly because the callback function at LoadFinishedCallback() in ModelLoaderAndroid.cpp is called. When this failure happens, there is only one controller geometry be added to the drawlList (DrawableList::AddDrawable() in DrawableList.cpp). I am trying to find out if it is removed by the culling mechanism.

@bluemarvin do you have any thought?

(Sorry for my ADB sometimes will interrupt the connection with the debugger, it makes the debugging work be more complicated to me.)

[bluemarvin]

I would look to see if the Device is some how disabling the model.
