説明
The painting component is 100% blueprints, it can paint colors on static, skeletal mesh in various ways at runtime. And you can also paint texture onto the mesh. You can also calculate the percentage of a given color by getting the data from the render target.
Attention！！！
Usage conditions of the painting component:
- Paintable mesh must have a light map UV channel (second channel by default).
- Paintable mesh must have physical assets that fit the mesh body relatively well.
