[Interest] [QT3D] Different level of lighting on desktop and android

[Oleg Evseev]

My application have direct light from top (direction (0, -1, 0)

On desktop Windows everything is all right:

but on android 4.4.4 scene is darker:

When I set ambient color of ground QDiffuseMapMaterial from half to maximum
(white color) scene on android get to look better:

but on desktop it looks too bright:

App on android 5.0 looks same as on desktop.

If I understand correctly it is due to different OpenGL versions - 3.1 on
desktop and android 5.0 and 2.0 on android, right? Is this a bug or feature
that should be handled on user side?

qt 5.7.0 branch
Windows 7 SP1 x64, Nvidia GT 630
Android 4.4.4

Thanks for help.
