I would like to stop this off-topic dispute.

I just sum it up: We both agree on most cases. But unfortunately you feel attacked and respond quite loudly.
So I only have to beg your pardon. I never wanted to attack you personally. This is just a dispute about clearly mentioned problems that appear when you try to make modern visuals (missing second uv-set in mdl file, problems with more than one textur / uv per uv-set, missing shaders). Those problems still exist and you cannot talk them away and not distract from them.

But those problems of a software have nothing to do with your personal character and are not intended to insult you.

Best regards,
Frank
