SF Version 1.20 Unity 5.2 Error MacOSX

It definitely shouldn't happen when starting with the PBR shader, it looks as if the error in due to a variable called "gl_", which doesn't seem to be allowed.

Yes basically - and simply creating a new shader with the latest version results in this. I've reverted back to 1.18 but yeah, figured you may want to be aware of this issue, it's specific to openGL.

As I say, the error occurs even when you make a new shader - so yeah, looks like something in the code gen has changed.

Happy to show you an example if you can't repro.

Cheers

Chris

Could you create a new shader with the PBR preset, and paste the shader error here?

I shall do but this may take me a few days - as I'm busy at the moment.

ShaderForge v1.20
Unity 5.2.1p1
On creating PBR Shader, under is occurred.
