Transparency sorting is always an issue, whether you use Shader Forge or not. I recommend using alpha clip instead of alpha

Use the transform node to transform a vector 3 from world to view

I would guess this is due to a collision in property names, and the fact that the shader still writes some properties, even when they're not used, such as your sliders. Try giving them a different name

It's most likely because the blending mode is still set to Alpha blended. Switch it back to off to fix it :)

I guess I should add an exception that verifies this, but, yes, it's a Unity issue :)

Was just about to let you know of the forums :)
Also, the wiki should be able to help you as well!

Glad it worked out!

Unfortunately I'm not sure what could be causing it. Try checking the SM2.0 option under the experimental category of the shader

Shouldn't matter, but, off, preferrably

It could have been too expensive. Try plugging in a value of 0 into the alpha, and a normal map texture into refraction, then try it on mobile
