Why is this happening.

I am attaching the image of my unity editor screenshot. Please tell me how to smooth these edges. I am using 3d model from simple town assets.

Whenever my camera rotates around I see this effect on the edges of the building.

 

Hey, if you need to smooth out the edges use Anti Aliasing. To do that go to: Edit > Project Settings > Player
Inside Other Settings tab you will find Rendering Path* set it to Forward (so you can use Anti Aliasing).

And if you still don't have smooth edges, make sure Anti Aliasing is on, go to: Edit > Project Settings > Quality
Here you will find Anti Aliasing set it to 8x Multi Sampling for the best quality (lower it for better performance).

Hope it helps

 

Thank you LMHPoly and Pete

It was indeed Anti-Aliasing problem. Fixed it with project settings and used the Anti-Aliasing 8x Multi Sampling and also with standard assets AntiAliasing.cs on the camera.
