I just wanted to drop this here for people to grab. It’s the unity 5 standard shader implemented in blender. I worked hard to make it look as close as possible, though it’s still a bit off. It’s good enough for you to create your procedural materials with the intention of baking them and exporting them into Unity 5.
I can’t wait to see what amazing things people use this for. Feel free to take these shaders apart and rework them to your specific needs.
