How would you work with two models in Blender if you've never used them before?.

If you have never worked with Blender and need to work with two models, you can proceed as follows:

1. Learn the basic Blender interface: open the program, understand how to load and save files.
2. Import models: load both models into the scene via the File → Import menu, supporting the required format (e.g., OBJ, FBX).
3. Navigation and selection: learn to navigate the scene, select objects, switch between modes (Object Mode, Edit Mode).
4. Basic operations: try moving, scaling, rotating the models to understand their placement.
5. Merging or comparing: if you need to merge models, use the merge function (Ctrl+J) or work with them as separate objects.
6. Use tutorials: quickly go through basic Blender lessons to understand the main principles of operation.

This approach will allow you to quickly get comfortable and work efficiently with two models, even without prior experience.
