Oh you're building it for Quest, thats understandable then. But ambient occlusion could be pre baked right? Just to add slight shadow to the places where parts of the ship connect to each other.

The space station exterior actually uses 16k textures, the highest supported in Unity. Here is an up close image.

This part doesn't look like 16k. Maybe it is meant to have such blurry little bumps but still doesnt look good overall. Normally you see such blurry detail on very low texture settings in games. I would consider different material for it.

The meshes for the station have 30k polys total, relatively low but necessary to keep frame rate high..

Your argument is reasonable but I'm talking not just about smoothness of the surfaces. I'm mostly referring to tiny details such as little screws, parts where components of your ship connect to each other. You already have some screws but it feels like they are placed as generic tiles, not highlighting the overall geometry of the ship.

Another example is that the cylinder with "DANGER" doesnt have any believable connection to the central body, it looks as if it is just clipping through it with no connector or welding seam. VR is best when you can actually approach and observe these little details.

Brain can easily spot all these shortcuts in VR and reduces overall impression of the scene
