Rule based assignments addon

Hi, I want to share with you and addon I've been working on. The idea is to automatically assign shaders, subdivision and visibility attributes based on defined rules. It is probably not very interesting for small, simple scenes. For bigger scenes or using assets over multiple shots for example, this can be very handy. In every studio I've been working so far, each department is separate and their work gets combined in a render scene with caches. Those caches receive the appropriate shader, subdivision, and visibility based on set rules. Long story short, let me create a little demonstration video. youtube.com/watch Also I should mention, this is my first ever addon created and first ever scripting attempt in blender, so the code is sh***t, but hey, it works, hehe. Any tips and tricks and support to make it more efficient, I'm all ears ;) dropbox.com/sh/x0v81239t0dap2a/AACbFosk6h77NZ2FWxGaOwJTa
