# Squared shadows after rendering

I would like to ask for a help. I have draw simple object with lights, but there was some squared shadows after rendering. (visible on the top and on the left side of the objects). There could be some consequence with size of the object (about 5mm). Unfortunately I have no Idea about solving Blenders sensitivity during rendering, antialiasing, or some other issues related with problem. Do you know how to fix this object? Thanks for replies!

EDIT: I have just tried to change the buffered shadows to the ray shadows. The result is much better, really big thanks for buffered shadow information, that in base solved my issue (image is usable now), but there are still small squares. Is there somehow possible to create image even better? (This is just for my interest now, not because of some real trouble) The image is shown below.

• Needs more information about your current settings. Are you using buffered shadows? – user2859 Aug 30 '15 at 9:17
• Thanks for reply. I looked on the lamps - there are several point lamps with ray shadows clicked on and two spots with buffer shadows clicked on. – user16786 Aug 30 '15 at 10:02
• The small steps you see are 1 pixel in width/height. To reduce the effect you could try to increase the Anti-Aliasing samples in the render settings. – user2859 Aug 30 '15 at 12:37
• As this is the Blender Internal, I think to lower these antialiasing jaggies you can render on higher resolution and then decrease the ouput resolution. Also a probale way is to edit settings in the Anti-Aliasing scroll – Mr Zak Aug 30 '15 at 12:53
• You could write an answer containing description what exaclty have you done to make it work for you and accept it so to show the problem is solved – Mr Zak Aug 30 '15 at 13:16
