Tetxure is not rendering as it should be, don't understand why

Hey there, my fabric texture is well rendering in every object of my composition except in the low part of the sofa, in the preview render it work well but in render i can see some glitch.

Maybe someone got an answer?

The object is alone (no copy paste that would make a glitch)

Thanks in advance guys :slight_smile:

If it has an UV map, have you checked it for distortion?
Maybe it comes from antialising, try switch it off.

Make sure there are no overlapping objects. Or the displacement map… :thinking:

It seems that it is not because it is only visible in certain parts from the view of the problem caused by the material or the denoise filter.

If you want to understand the problem, you’ll need to check the object before you.

Yes i got an UV map and the distorsion ar not strong so don’t think is that, just tried without antialising and i got the same

No overlapping objects :frowning: what could be wrong in the displacement map?

i think it’s coming from the denoising but i don’t know what i can do to fix it

How much samples, maybe increase samples will help.
But i think if you try improve the uvmap might slove it too.

Just made a follow active quad on my UV to dont have distorsion but it’s making the same

I render with 250 samples

Try double the samples and see if it helps.


that’s with 1000 sample it helps but i still have some strange pixel glitchs

Even if you zoom in and look closely, it doesn’t seem like a rendering problem.
If you don’t mind, just the parts that cause problems.Please upload it to the blender file

Here is the file, big thank for your help!

I think there’s something wrong with Normal Map

Add…

Some objects have their normal flipped.
