Yeah, they are extremely high, But I was desperate. If you open the last image on a new tab it will open on full resolution (it's actually downsampled but it's enough to see) you will be able to see that the corners of my model are aliased just as if the amount of samples were too low, but now I know that the problem is not with the render but rather with the renderview on maya, I think I got so frustrated When I saw this that I didn't even thinked about exporting the render and open it in photoshop and when I did it I found it was just fine. Then I found that if I zoom-in the rendered image on the renderview more than 100% it fixes the aliasing too I mean it starts pixelating the image but I can no longer see any imperfection on the edges of the model.those settings seem extremly high, can you post some pictures of what issues you are having?
