I've found that a mesh in my scene has huge uvs.
Because of this, I am getting weird artefact as seen this image.
Value of a certain pixel after render (with denoising):
Value of the pixel after uvs normalized (uv coordinate value clamped to 1000).
This couldn't have been due to denoising as I've disabled denoising and confirmed that the pixel still get high values.
So, my question is, why is changing uvs effecting the light value of a pixel in cycles render by such huge magnitudes?
Also, here's the node setup for my material if it's relevant.
