If you have a big open landscape. How to make distance lands visible blurry or something. Or how to make distance land background. Any idea where can I start?
Hi, there are a couple of options.
Actually, if your texture has a resolution of the power of 2 (such as 1024 * 1024) then the engine generates Mipmaps which essentially do exaclty that: Make the material blurry in the distance).
If that is not enough you could use the “scene depth” component of the G-buffer within the material use that to drive a Lerp between a high and low-res versions of your textures.
Are you talking about distance fog / atmospheric fog?
No. Fog is something else. But it may help you reach your aim.
