Dear pbr fans.
I received a lot of feedback regarding the website and content itself and will take action in near future.
Things that will change/improve:
1. Include all textures for pbr material in zip rather than unity package so can be used in various game engines without having to install Unity3d.
2. For Substance materials include substance file
3. Include Roughness texture
1. Adding item to basket should not redirect to checkout
2. Bigger images for materials so it will be easier to preview them
