Hi guys .

The texture in the foreground is getting distorted when I render in camera view .Texture size is 2k for foreground grass texture .The camera is rotating from -45 to +45 .. ( hats my requirement ) .. can anyone help me out with this . I am uploading the image also for better reference for the problem .

Thanks in advance ..

what do you mean distorted?

Are you talking about how it's getting blurry as it gets closer to the camera?

actually the camera movements are not needed . i just need to take some still renders and the renders show me foreground blurred .

Well, unfortunately you probably don't have a high enough resolution image. When dealing with huge plains of grass and what not, it gets rather difficult when you get close up on one spot.

There are several fixes for this. One is to use a higher resolution texture or repeat the texture several times. However doing this you will probably get moire patterns as you get further back, this can be fixed with more samples which unfortunately really hurts your render time.

Another thing that might help you a little bit is try different filters. On every file texture node there is a "filter type" that is usually set to quadratic, just try some of the different filters and see if you can make it work for your scene.

Another thing you could do is project a colored noise in the area around the camera that has an alpha that falls off as it gets further from the camera to simulate there being more detail.

I don't know, there are several things you can do. I may not have even listed the best ways but these are a few simple ones you can try.

Good luck.

Yea I agree with Gravid, looks like you have quite a large model of the golf course and if thats only using a 2k map for the whole thing well there just isnt enough detail there. Apart from using a bigger map, or multiple maps in a layered shader, you could see what results you can get procedurally? Or maybe a combination of the two approaches?
