Still black and I do not detect any error in the Visual Studio log.
Unfortunately it doesn't work.
Here is a simple material that becomes black on Nokia Lumia 1520.
If you have any hint on different shader settings I can do further testing.

The "experimental Shader Model 2.0 force feature" works for me :)
Hi,
I have installed the beta 0.33 right now, and the editor works fine.
You are my man!
I've created the shader with the release 0.32 but I can ricreate it.
I will use the actual shader to test the 0.33 release, I'll keep you updated.
Change the lights color and auto rotate checker.
Easy and useful options.
:)
For more complex stuff we can use the classic Unity scene viewport.
Yes, but the WebPlayer statistics says only 8% of users have a shader model 2.0 video card, so we so decided to ignore the problem.
I'll do a test tomorrow on other computers and let you know.
