I have a question, I have created an environment with mountains and stuff,
but when I’m at a certain distance the textures fade out and become blurry.
This is really anoying I want them to be clear at all times.
That “blurring” and “fading out” you see is actually a 3D graphics optimization technique called level of detail (LOD). I suggest you read up on it as it is a very essential topic in 3D video game development.
If you want to modify LOD, you’ll need a pro license. Follow this guide.
