weird artifacts with render in cycles this is what happens when i render in cycles, this is the only part in the whole render that does this. i tried increasing the samples and it did nothing
That appears to be artifacts from the denoiser. Try disabling the denoiser or tweaking the denoiser settings to reduce the artifacts (reducing Radius and/or Strength can help).
Alternatively, such artifacts can be caused by saving the image in a 'lossy' format (such as JPG) with too low a quality - check your Output format settings.
