I am new to blender and i want to render some images with transparent background. This image is rendered with cycles and the shadows are generated on a plane with Shadow catcher.
The problem is that the edges of the objects come out with noise. I tried different lighting methods, higher number of samples but nothing helped. If i render with background then it looks fine, there is no noise.
I want to keep using Cycled to have it looking as realistic as possible.
In the belwo image the white background is added in Gimp.
