OK I'm finally able to export objs with textures ect but the oposite tool option disappeared, for example I remember the oposite tool to inflate would deflate but I can't use that anymore and the shortcut is gone... I didnt want to flood the site with questions so I guess I will post all my future questions here.
If you are in paint, then that would be why. You can't do any more adjustments or sculpting to your piece once you take it into the paint area. If you wanted to do additional work on it, you have to open up your original save (or when you open up the save with color file, say no you don't want to go to the paint area). But, you then would have to start from scratch with painting again.
