This is a little obscure, but here's the gist

I want to be able to provide an easy way to browse one of the best free PBR material libraries there is.

In the current vision, this includes

• A simple "Open AmbientCG Library" button you can add to any of the shader properties to make it visible somewhere
• A way to define the texture names and channels the source textures should map to
• A cache implementation
• A way to select the shader you want to use (maybe auto-map foliage to cutout, etc)

Currently it can browse, download and set up the ORL Standard materials but its not the best User Experience just yet

• Add a popup window to browse the material library
• Add Search with pagination
• Add an ability to download materials
• Add caching support
• Map materials directly to ORL Standard
• Show materials already in local library
• Add support for selecting the type of shader used (regular, transparent, cutout, etc)
• Clean up UI
