The Ptex is a texture format, and Walt Disney Animation Studios created it.

Hi @alexchicn — We don't currently have plans for Ptex, but are working on the KHR_texture_basisu extension. It uses KTX v2 as a container format, and Basis Universal as the internal compressed texture format. A major advantage of that approach is efficient compression and compatibility with any hardware. I don't know about Ptex specifically, but most older GPU texture formats work only on specific types of devices.

It is also possible to write custom extensions for behaviors your application needs, as Microsoft did for the .dds texture format.
