When sharing and reviewing your 3D models, there are some important factors to consider for an effective and enjoyable process. Firstly, you should know who you are sharing and reviewing your models with, and what their expectations, preferences, and expertise are. For example, if you are sharing your models with a client, focus on functionality, usability, and aesthetics; if it’s a mentor, focus on technical, artistic, and conceptual aspects. Secondly, feedback should be constructive, specific, and respectful. If you’re giving feedback, use the sandwich method - start with a positive comment, then give constructive criticism, and end with another positive comment. If receiving feedback, thank the provider, acknowledge their points, and request clarification or examples if needed. Lastly, use the feedback to improve your 3D models and skills. If the model has too many polygons for example, reduce the polygon count or use normal maps or other techniques to optimize it. If proportions are poor, use reference images or guides to adjust the model.
