AFRAME Enviropacks

A simple way of adding high-definition-looking environments and materials to your A-Frame project.

Or could also be a "raw" material: Fabric026, Metal009, Metal035, Plastic, Snow003, Snow004, Wood027, WoodFloor041, aerial_grass_rock, bark_brown_02, brown_planks_04, forrest_ground_03, mossy_rock, rock_05, sandstone_cracks |

Physically Based Matcaps

This package registers the pbmatcap shader, which creates a "Physically Based"
matcap material. The pbmatcap shader uses material textures (such as roughnessMap and metalnessMap textures) to mix between custom matcap textures created for each different environment.

pbmatcap shader can approximate the full THREE.js standard shader while giving performance acceptable to a mobile device. By default, the enviropack components will automatically switch to pbmatcap on mobile, or standard on
desktop. This behavior can be overriden with the shader property of the enviropack-material` system.
