Hello! Good evening! Your work is great! Could you tell me how you created the Olive's Bob and Stacy's Bun hairs so they no longer had the bald spots? If you followed a tutorial, could you link the tutorial? I have some basic Blender and Milkshape knowledge.
Morning! For Olive's Bob all did was duplicate some pre-existing planes to cover the bald ring patch. Stacy's bun required making a new plane to patch the hole in the top of the head, and then two more for the bangs where they were supposed to meet under the hat. After that, it was just adjusting the UV maps as needed.
Although, the alpha for Olive's bob was misbehaving with the planes, so it did have the extra step of manually relayering all the planes so they wouldn't look funky anymore. And I mean ALL of them. Had to separate and deconstruct the hair section by section, and I think it was around 7-8 groups when done so that I could shuffle them and merge them back into one group mesh again. For patching holes in hair, it's just deciding what will be best and easiest without pulling your own hair out. In some hairs it'll be easiest to duplicate strands, although the easiest ones are when they're just flat shells save for some details, like the bun was from my limited experience with hairs. Some hairs have odd quirks that make them a bit harder to work with than anticipated, like the braids I've been away from for kids. But it's more in trying to get the hairs to sit close to the head and morph well with the body if they hang low enough. The best way to start working on a hair to patch a hole in it personally is to deconstruct it into two initial groups. The parts of the hair with body (what may be the fluffy strands) and the hair shell (could also be called the scalp, but it's got hair textures, so the real scalp doesn't peak through I believe). From there, it's easier to see what you're gonna need to do to patch the hair, and whether you'll just need to copy pre-existing sections or make brand-new ones. If you need me to elaborate further, please let me know. I know this is more like a brief overview on how I did those hairs, and try to work on them in general.
