Hello, So I created this Figure and want to add a smile on it but can't figure out how. I tried to use UV's but when I select everything it looks like a hot mess on the UV field, thousands of dots pressed together.. I couldnt scale the texture of the picture that way. Then I marked areas as seem like the red lines on throat and arms, still a hot mess of dots after selection. What would be the best way to add this smile on my mesh?
This is a basic low-poly figure similar in shape to yours. It wasn't sculpted, it was modeled starting from the default cube. The topology is all-quads (although some of the poles may need to be moved for best animation, this should be sufficient for an example). The red lines on the model are edges that have been marked as seams, which means that during unwrapping they'll be separated into different UV islands. Because the model is low-poly with simple edge-flow, the edges can be far more easily selected and marked as seams than on a raw sculpt:
With the model UV unwrapped, an image texture (including facial features added in a 2D image editor such as GIMP) can be used:
In Blender the Subdivision Surface modifier can be used to simulated the appearance of a higher-poly model. If the model is being exported to another application, either the target application's subdivision can be used (if available), or Subdivision should be Applied before export:
