A lot has been written. In short:
To extract models from version 6, you need to install a pirated copy. Then it will work. Who is willing to help?)
I would be happy to extract the models from version 6. I have a pirated copy and 3ds Max installed. Just tell me how to do it. I will be able to dedicate myself to this properly in about a week, but for now, I'm waiting for instructions.
