I'm an artist, and I'm interested in seeing how well I can turn some of my existing artwork into clothing textures for SL. I've never done this before, and have very little experience with 3d stuff at all. I'm hoping, at the very least, that I can competently put pictures I've already drawn onto simple Tshirts to sell for like 1L$. I made a very quick texture to test (file attached) and wanted to preview it in-game. I don't have the 10L$ to upload it for real, and the preview image in the upload box didn't look right (screencap also attached). Is there something else I should be doing with the texture to make the colors come through right?
I'm also looking for general advice and guides on clothes making and selling. As I said, I'm currently looking to just use existing artwork as textures. What should I expect from the SL marketplace, customer preferences, etc.?
(btw my tester image is a recreation of a shirt I have up on Redbubble)
