Quote - when your camera is close you get say 6" x 6" area in a 600 x 600 pixel image (for example)  that gives you a nice closeup of your pattern

when you pull the camera back you now have say 12 feet of scene display and still 600 x 600 pixel image. There may simply not be enough pixels to display the pattern.  By getting only parts of the pattern you get a mess.

Making the image bigger will help. I started with 640 x 480 images and when I went to 1200 x 700 things got better.

Check for distortions in the uv map as well.

Bagginsbill is the one to answer this one I think.

Quote - Looks like you are trying to make a pattern in cloth?? have you looked at Bagginsbill's loom? it can make all sorts of weaves for cloth

Thanks for you answers.

Yes I tried to make pattern in cloth. I wanted to create my own pattern whichh can be used in most renders, not only in closeups, high res pictures or with final renders. I cannot recommend to use advanced render properties or create hi-res pictures with my props.

I wanted to create some procedural, fabric patterns for my props, not using "native" Poser patterns nor BagginsBill matmatic looms or leather.

Of course I've read most (all) BagginsBill tutorials, but they are not os simple as I thought. I spent more then 12 months trying to check and understand all nodes, but my brain has 30 nodes limit ;)

I think that picture resolution and number of pixels is not major problem. The same pattern looks different on 2 meshes. P4 render or render with lower shading rate looks better, what means that pixels number is not important.

I hoped that BagginsBill or somebody familiar with mathmatic and nodes explain me that I should use "gain" or "bias" node for example and explain what I did wrong.
