I got a really an annoying problem, every time when i want to Bake an Ambient Occlusion blender gives me always hard edges.

I search a lot around for tutorials, but nothing have worked, how do i Bake a SMOOTH Ambient Occlusion map?


Not enough info as you have failed to supply a link to your .blend file !

What are the modifier you are using and waht are its settings, is it enabled for rendering
How many samples are you using for the ambient occlusion ?
