How to rig a vertices 3D model?

To rig a vertices-based 3D model, create a hierarchical skeleton (armature) and bind vertices to bones using weight painting—this defines how much each vertex moves with a bone. 1. **Build the skeleton**: The armature acts like a character’s bones, forming a control structure for movement (e.g., a wrist bone controls hand vertices). 2. **Weight paint**: Assign “weights” to vertices so they follow the right bones—this ensures natural movement (e.g., hand vertices stick more to the wrist than the elbow). For beginners, start with a simple model (like a cube) to practice armature building and slow weight painting—this avoids overwhelming complexity while learning.
