I'm modeling a simple scene of black board (diffuse material) with red, green, yellow, and white squares (emission material) on it.
The following is a crop of the rendered result.
All the squares I modeled have same size, however after rendering, the last square shown in the image is smaller than the rest. One square has a lighter edge (marked #1). I think this has something to do with anti-aliasing used in Blender cycles. The following is my rendering setting.
I want all the squares to have the same size in final rendered image and uniform color even in edges (like the first 4 squares shown in the image above). I was searching for a solution but couldn't find one. Can anyone suggest a solution for me? Thank you all in advance.
