For example, if you take a greyscale image of a white cube on a black background and apply it through Spotlight, it will create a cube of that shape and size. What’s different is that the textures, rather than applying anything to the model below, allow you to convert the image to a 3D model as a subtool.
Snapshot 3D works in the same way and as part of the Spotlight wheel. It came in the form of a wheel that, when activated, allowed you to place the image or portion of the image over your model and then paint through, adding the texture to the surface below. Spotlight was introduced to allow an artist to take any image (texture) and project it onto the surface of a model using Polypaint. Snapshot 3D is an enhancement to the functions found on the Spotlight wheel. Having used it for a few days it is a massive help in organising your creations, and it seems a shame that we only have one folder level and we can’t nest them (yet). The ability to move, scale and rotate the whole folder is a real bonus. Subtools can be placed into folders and there is even a folder setting button allowing you to access lots of folder actions like delete, transpose, merge and Boolean. Good naming conventions helped, but a true folder system was needed and that’s now been added. This becomes a real issue when you get into hundreds of subtools per character. One big gripe with the subtool system in ZBrush has always been that you can’t easily group and manage your subtools effectively. This latest version works better for hard-surface models as it can detect sharp surface angles and even maintain creased edges, as well as giving you polygroups.
