X3D Multitexture needs a complete review of current capabilities to ensure that proper support is required.

X3D Specification and Possible Technical Issues

Multitexture capabilities are defined in the Texturing Component of the X3D Specification.

Technical problems and issues

  • Yvonne Jung reports
    Having multiple textures for shaders is possible, but the compositing modes defined in the spec
    basically exactly map to some around >12 year old GL extensions from the pre-shader times.
    So, no, it won't supported in that way.
