yes, looks like it is missing. I think it should make use of
glFramebufferTexture for the cubemap array case though.

I think OSG::TextureBuffer is the one that should use
glFramebufferTextureLayer (for cubemap array and similar cases) to make
non-layer attachments. To me that seems in line with it's other uses
where it binds a plain 2D image as the attachment.
Since you have a use case for these, you are likely in a much better
position to verify changes. Can you adjust the changes to
TextureBuffer/LayeredTextureBuffer to be in line with the above? Thanks!
Cheers,
Carsten
