I have been in your situation. You want that sweet awesome look but it’s not working somehow. Well, the sad news is, there’s no magic hotkey or words or instructions. In the end is just presentation, composition, lighting, etc and each situation is different. The most important is lighting and shine. Remember that things reflects the environment and if you have a dull environment you wont have nice reflections. Also the way the logo is modeled is important, you need that great topology to have good bevels and catch the light. So it’s a tough dance between moving lights, your model, environment, composition, background, color grading, etc. Try things out, grind away, don’t give up.
