If the texture is a bitmap, remake it at a larger resolution.

Ok, on the reddish color i had a little texture, i have removed. But one the white one it`s just simple white color.
As you see in this example ( where the red doors approaches to the white carcase it's more obvious)
I want to mention that this picture was made in a short time of rendering( around 100-150 passes), but even if i let it for 4000 passes the fuzzy lines are still there.
Quite annoying.
Thank you for your previous answer !

Render bigger resolution 1920 at least.

I'm not sure what OP means by fuzzy lines, but if it's about sharpness, one can take a look at image and/or texmap filtering settings and do additional sharpening at post production stage.

Sorry if i misunderstood question.

My guess is OP means the anti aliased line and refers to it as fuzzy.
This is unfortunately the mathematically perfect representation of a line through sampling and averaging. We are bound by display pixel density and the fact, that we represent a mathematically perfectly straight line.
This issue, among others like moiré patterns and very high intensity samples against dark background not averaging to an anti aliased line, can only be solved by either image filters or in some cases super sampling.

You can try: double image filter size, render at 4x the resolution (twice height and twice width) and scale the image back down using bilinear image sampling to original size. This may help in this case getting rid of the fuzzy line, but in the end you are bound by the pixel density of your display. You can only get so mathematically perfect, before in Apples words "non retina displays" screw you over.

Otherwise, the standard method of avoiding these fuzzy lines is simply image filter increase the classic way.

edit: you can increase you display's pixel density by stepping back a meter, that should get rid of it :D

First of all, thank you all for your great support.
With your help managed to get rid of the anti aliased lines from my scene.
After 280 passes at 1280x720 resolution i have this image :
Now i have so much noise in my scene.
Any tips to have less noise ?
Thank you for your pacience.
Have a great day all !
