Setting the default vertex attribute value

General Discussion
1

As an example, if I were to omit the VertexBuffer.Type.Color buffer from a mesh, then it is still possible to read the inColor vertex attribute value in the shader - it will simply be defaulted to (0, 0, 0, 1).

The “Non-array attribute values” section of the opengl wiki indicates that it is possible to change this default value to something else. Does JME support this setting in any way?

I guess, it does also say that “Note: It is not recommended that you use these. The performance characteristics of using fixed attribute data are unknown, and it is not a high-priority case that OpenGL driver developers optimize for. They might be faster than uniforms, or they might not.”, so probably better to work it out with uniforms anyway

…or defines.

Whatever you are trying to do, there are better ways to do it.
