How to achieve very sharp and noise free renders for exterior scene

[Sarthak]

Hi, a question to the forum

I never get those perfect clean sharp renderings for my exterior scenes.

I am attaching a scene, which was rendered on 2250 x 1800 pixel for noise 5% and it rendered for 20 passes. I am still not getting desirable results.

Some tips would be great.

Hi,

Both metrics, 5% noise level and 20 passes, are more suitable for preview images rather than for final renders. Try to render for longer and aim for lower noise level. If you can't afford longer render times, then consider using denoiser.

Regarding sharpness, to my eye your example is already quite over-sharpened, but you can always crank up sharpness filter directly in Corona VFB, or sharpen image additionally in photoshop if you wish so.

In terms of "sharp" it also looks like there is Bloom and Glare which is at a low enough threshold that the sun-facing parts of the buildings get it applied and this will naturally mean those areas look softer as they have an aura around them.

Thank you for replying,

I tried rendering it for 45 passes which reduced the noise to 3 %, but still while zooming in you cannot see the details on the wall.

I am attaching another file whose result I am trying to achieve,

Do I Increase the resolution?

Increasing render resolution will certainly let you see more details on the wall, yes.
