I've created a model, and I'm preparing to texture it. I've marked all the seams, unwrapped it and moved it around to my desires. I am ready to create an image for my model. Usually, I would see people creating the texture, then align the UV unwrap to the image (of the texture). In my case, I only have the unwrap. I do not have an image file (a texture). I am looking to create an image file of my UV unwrap which I can use to place a texture on. Maybe have the islands in white, and the rest in black? I am not sure how to approach such an idea. How can I create an image of my UV unwrap; an image that separates the islands in a different color in a way where I can texture it? Thanks.
The default exported PNG image will have a grey outline of the UV map filled in with transparent white. The rest of the image is also transparent so you can put it over top another image in a photo editor like GIMP and still see the image underneath. Good luck.
