texture baking problem

i have normally bake from the model if the model has a repeating section . Which can be found on a fence . you can make normal map just 1 part of the section. you can dowload my security fence model and you will find a normal map . this might help you see how small section was used to make the process

Hi irgum76,
i guess, nobody replies because it is hard to understand your problem. Could you show some pictures, screenshots that would help to better explain your problem.
