Perhaps a stupid question but, is it so difficult to make a Poser version ?

The work involved for building and a set of materials, yes. Keep in mind you're doing the work twice, and maybe getting less than 1/5 the return. I worked in the spectacle and I had also a company, I learned you can't expect to win every game, but the main thing is to keep your customers !
