this was a great help, I had run into the same issue. doh!
other feature idea in the same vein would be the ability to 'save as' & 'rename' shaders. So there's an ability to branch off a working shader and experiment without ruining your original.
bingo! this is exactly what's been plaguing my workflow with using Candela - there needs to be a way to adjust the alpha in the diffuse slot for reflection intensity. Unity shaders as well as Lux shaders support this. Would be awesome for SF to as well. cheers
Cool, thanks! I hacked it up and still not getting Shader Forge to load. I'll just remove the shader for now and start over. :D
