And secondly, I heard that it's good to let user to "test before buy". In software market, I know that it's done by making "trial version" of the application. But I don't know how this is applicable to 3D models and texture. Do you happen to know something about it?
Lastly, sorry if my english is bad. It's not my native language. I hope you can understand the questions and clear my curiousity. Thanks before!!
Best regards,
