I've been creating textures and opacity map items for a great free 3d instant messenger chat program called IMVU for several months now. I typically use photoshop and open canvas to create custom textures to pre-created objects such as skins for avatars or in this case a 3d object that allows you to manipulate it's shape via an opacity map to create a unique product. I'm quite happy with how these items came out and I hope to start producing my own 3d products soon. The products I opacity mapped / textured are : The beak, the eyes, the ears, the wings, the skin, the loincloth and the wings.
