Hi there, I can’t be the only one who finds is very difficult to preview the Materials available in the Material Library, they are far too small IMO. It would be great if it was possible to adjust the size of them.
Thanks for the Feedback @rheinason , as always, feel free to also forward it through our portal to PM directly.

And to be honest, I think your inhouse artists could probably design a much better sample scene than the sphere we have now. It’s not well lit. I recommend taking a look at the samples from other libraries like http://www.poliigon.com or even the automatic material thumbnails in Blender. They spend some time really crafting their ‘default material ball scene’ and it really shows.
