"Back with a review!  \n\n\n\tAt times I do models on Sculptris to later on edit them for some PdN piece and the background gives me some trouble. I'm aware I have other choices to pick from, but Sculptris is lightweight and relatively easy to handle for someone with budding 3D-sculpting skills and an outdated computer, despite its several shortcomings. To name one, I can save a capture as a transparent png, which is not exactly the case because in fact the background is saved as black and what I do want is full transparency. So, my seemingly only chance is to save the capture with the program's interface's background included, which is a sort of dark gray to black gradient, and then see how I manage to remove it. In the following example I couldn't seem to adjust the magic wand's tolerance to a value that wouldn't mutilate parts of the creature, especially below the left armpit and above the left side of the head. The solution came from picking a color in the vicinity of the difficult area and playing with Value Tolerance and Gray Upper Limit, leaving all other settings at defaults. I'm glad I had this plugin and glad I discovered how to use it for this particular case  \n\n\n\t \n \n\n\n\tFollows a side-to-side view of the non-transparent original capture and the result after removing the somewhat tricky gradient background:\n \n\n\n\t \n \n\n\n\t "
