rendering texture wrong
I get strange results after rendering for the texture of the fabric. I made already different versions of 3D maps but cannot get it right. Strangly in the previous version I never had this problem. Anyone an idea what it can be? I added the rendered 3D window and the final render picture.

Nathalie, can you share the texture transformation information of the normal map and the texture map? It might be that your normal map has a different scale than the texture (diffuse) map.

Of course Pablo, can I send them to you by email? the files are too big

You can simply share screen shots here of your settings in CLO where the fabric's properties are. Especially I'd like to see the scale of your normal map vs. the texture.

ok, I took screen shots

Expand this one please. Also. you seem to have a displacement map. Is that on purpose?

I wanted to use the displacement map to give additional depth to the fabric. But you got it, I tried lowering step by step the displacement map and finally deleting the map gave the best desired result after rendering. Probably because the fabric is rather fine, it is better not to use the displacement map? The transformation has all the same dimensions for the different maps 200x200 angle 0
thanks for the help Pablo!!!

You found it. It was the displacement map. For finer details, like the surface texture (not the color or pattern), you should use a normal map. Displacement is a feature that adds geometry in the rendered view according to your displacement map. Normal maps are a visual illusion of depth, a displacement map actually creates the geometry so depth is real when rendered.
The caveat is that fine details do not work very well with displacement. It is kind of drinking out of a firemen's water hose. Too much for something that is better accomplished with an illusion like the normal map.
Here is a nice explanation

Thanks for the article, I didn't realize displacement do not work well with fine details.
Strangely before I added always a displacement map and it worked well with fine details. The picture (here low resolution) is from such a project (in high-resolution great details). When I rendered last week the same fabric with displacement map it got also a bumpy image. The only thing that changed is an update from CLO, all the rest stayed the same.
Anyhow, I just leave displacement out for now ...
