Light doesn't work

Hi everyone,

I have been trying this 3d library for a few days and it worked on my PC, but when i try to run a 3d scene on my tablet, everything is black.
I think the light doesn’t work on my tablet.
Even with the basic scene, everything is still black.

Could someone help me out?

Do you mean that when you open from tablet, for example, https://playground.babylonjs.com/ , there is no light in the scene?

Yes. everything is black. no matter which demo I try.
I have also downloaded the full zip from github and from there it doesn’t work too.

Might need engine.getCaps().highPrecisionShaderSupported = false;

Try some of these PGs: Babylon.js Documentation

It worked!
Thank you.
