Most AI skin tools hand you a picture of a character.
SkinMaker draws each body part as its own panel, then packs
them using Minecraft's real UV layout — hair included as a
second layer — so you get a working 64x64 texture, not art you
still have to trace.
The other half is delivery: a Bedrock .mcpack with geometry
matched to your arm width, HD upscale to 256x256, a labelled
UV sheet, and 3D renders from four angles. Those tools are
free, run in your browser, and need no account.
