No kidding! Wow it’s been a while since those who love the mining profession have received any new stuff, lets see what they’re getting with the new expansion:
The team has been hard at work creating new meshes, normal maps, textures and shaders that work to communicate the complex composition of each Ore with a unique style. Our artists have been painstakingly sculpting new meshes from which we are rendering all or of our Normal Maps, Ambient Occlusion Maps, and Depth Maps while others researched and built textures to represent the minerals peeking through the cracks of each rock.
Try to contain your glee.
