Nvidia Shield Android TV

Hi,

Im trying to package my project using Unreal Engine 4.7/4.8 compiled from source code. Both versions have different issues with the device

I have set-up my development environment in the same way for Shield console as I did for my Shield tablet and I have started running into problems.

On 4.7 the editor shows the option to package for es3.1+aep and will compile the project. However when installed on the device using the .bat the installation completed successfully however the screen is completely black. However es2 rendering is fine.

In 4.8 I can see the option for es3.1+aep in the project options (this is not greyed out) and is ticked however there is no option in Package Project>Android for es31+aep.
I do however have ASTC as an option.

Is Tegra X1 currently supported by UE4?

Regards,
