Smudging Textures / Lighting in Cycles

Support Lighting and Rendering
1

Hey everyone, I am in need of help!

I set up an interior Scene and added lights (IES Textures ). On the left side the light works fine, the texture is sharp but where I marked the spots it’s completely washed and smudged althoug I am using the exact same lights and the exact same textures ( the topology is all quads on a cylinder , and in EVEE it looks fine and sharp).Checked the normals as well, they are correct. As soon as I am rendering it out in cycles it goes nuts. Rendering settings: 512 Samples/ 0.01 noise Threshold / Denoise ( Although I tried out nearly every combination by now) .
Does anybody know what causes this

Check if that object is properly UV unwrapped, and shader texture coordinate is set to UV. Even if it is a procedural texture.

Thanks , that was the issue indeed. I forgot to UV unwrap it after I sub div’ed and manipulated it !
