IMVU is like pyramid selling. people make meshes, the 3d artists, programmers. IMVU have a base price of 250 credits and on top of that you the meshers put there profit. You can edit there mesh and add your own textures and set your own price so 250 to IMVU + plus mesher profit + plus your profit = selling price. Credit can be sold out of the game either selling yourself or by going thru a reseller. Current rate is about 45% 250 credits is about 10-15 cents.

"And how do people who are not skilled earn in that game?"
Generally they don't they steal textures from google or make music products using ripped mp3's, sorta like doing a porn site with ripped content.. you make think your onto it but you will NEVER make serious cash by doing it that way.

90% of those deveoping are just looking to make extra credits to spend in the game itself.
