I just wanna point out that this may sound easier then it actually is.
Pricing to sell isn’t always easy because you have to price it to sell all while making it so that you actually make a profit.
As the title states; lazy devs aren’t always a bad thing…
Now, yes some stuff that you have spent a while on you may not want someone to just derive from and take the credit for making, but the fact is that you are still getting credits for the sales that they are getting even though they just derived from you and didn’t make any changes.
Meshing is usually a good way to make credits on IMVU.
See, how it works is you make a something referred to as a mesh using a program like 3DS Max, Blender, etc. and make something 3d for IMVU, then derive from products that are by IMVU; and people will over time derive from your product if they like it.
