We certainly have more options for X3D extensibility than ever before, now that we've achieved the X3D 4.0 Architecture. It is also much easier for Web3D Consortium to consider recommendations for incremental improvements to our specifications.</div>

I agree BlendMode is worth adding to the spec, but *not* with all the<br>
enums. The enums currently available match all OpenGL / OpenGLES /<br>
WebGL capabilities, but it implies a lot of possibilities and I think<br>
only a few are really practically useful for users. I would like to<br>
research what is supported in this regard by Vulkan, Direct3D, and<br>
choose a "common subset" for the spec.<br>
<br>
Of course particular browsers could still extend allowed options to enable more.<br>
<br>

Michalis<br>
