### Legal/IP/license stuff
Basis Universal uses texture compression formats or technologies created by several companies: ARM Holdings, AMD, Ericsson, Microsoft, and Imagination Technologies Limited. All are supported by various open standards or API's from [The Khronos Group](https://www.khronos.org/), such as OpenGL 4.5, OpenGL EX, or Vulkan. The ASTC texture format is the only standard we could identify that is covered by an explicit end user license.
