Improving Environment Quality

[stray summit]

I recently bought a low poly city asset pack (https://www.fab.com/listings/df946d23-476a-4d79-adc1-4dc6ba1b3870). I'm running into an issue where the quality of my scene is obviously worse than the showcase images and videos they provided on the listing website.

I attached a picture of what mine looks like. This is a pre-rendering - i've been told however that the camera view in the unity tool and the post render look are the same? Not too sure.

I've done simple lighting work and that's pretty much it. I'm pretty new to unity if you couldn't tell. I guess the most pertinent thing I'd be looking for help on is maybe the shaders or rendering process? I think the shaders could help a lot but I frankly have no clue.

Would appreciate all the help. Thanks!!

The first thing that stands out is lack of shadows in most of the scene. I can see some towards the bottom of the screenshot, but they fade out. Increasing the shadow render distance could help. But I'd assume that in the preview they're using baked lighting/shadows.

Another thing that stands out color vibrancy. This is likely due to them using some kind of color grading/tuning post processing effect. Might want to see what effects are included in unity by default and play around with them.

Well the look it honestly depends on the feel you want to go for. You just need to play around with lighting, colors and post processing

Maybe fog as well

The lack of shadows definitely makes the image lack depth. The promotion pictures seems like they have some global illumination solution (like ray tracing or UE Lumen) enabled which can help the soft appearance.

There also seem to be some high quality reflections, either ray traced or SSR

Likely pre-rendered with path tracing to present them as favorably as possible
