When adding details, how do I know if I should model them as a part of the mesh, or use a normal map (or other textures)?
I know this is an opinion-based question, so let me try to narrow it down. For example:
Can we make these grooves with normal map only? And if so, what’s the pros and cons for texturing instead of modeling them?
A more complex example:
If someone asks you to make a 3D render like above, how do you know which details should be made as geometry, and which to be on textures?
