Hi,
i would like to report a serious bug. This has been verified with the asset store modeltargets sample and the latest Hololens ModelTargets beta sample.
When you specify the 3D guide view and override detection position, then the reset tracking button(essentially trying to reset the tracking) throws an exception the second time you perform it.
Please fix this is a serious show stopper for Hololens. The error does not happen when a 2d view is used or when the override detection position is not checked.
Thanks
