Inspector exceptions when built-in shader is selected in the editor (v1.7)

Andy Buchanan 9 years ago updated 9 years ago 5
I'm developing a shader remapping helper, but when I have one of the built-in shaders selected in an ObjectField ( e.g. "Standard (specular)" ) I'm getting the console spammed with this:

DirectoryNotFoundException: Could not find a part of the path "E:\Wish\Perforce\X\Main\Game\Unity5-PS4\Resources\unity_builtin_extra".

If you mean Shader Forge 1.17 - update to 1.19 and it should be fine, unless this is due to something else.
Yes v1.17. Cannot upgrade yet due to the other problem; can't go to Unity 5.2 for a week or two.
Think this is a different issue, because the other problem was on v1.18 not v1.17

It could possibly be that perforce is disallowing access to the file or something?
AFAICT the "E:\Wish\Perforce\X\Main\Game\Unity5-PS4\Resources\unity_builtin_extra" does not exist when in the Editor, it is only created when the project is built. I think the Unity editor secretly patches though to the master copy in $Unity/Editor/Data for it's usual operations. If I had to guess, I'd say you can't load the built-in shaders code with the same method used for normal project shaders?
Still throwing an exception on v1.19 and Unity 5.20f3
