How to make patch edges invisible but still effected by lighting?

Hi, I am plotting a voxelized model using patch command. I wish to remove the edges. so i set the property edgecolor

set(patch_handle,'edgecolor','none');

however this created the undesired outcome presented in the image (dotted lines) then i tried giving the edges the same color as the patch but then they were not affected by lighting. so i guess my general question is how to plot the images in a continuous manner or more specifically, how to make the edges invisible and not get the dotted outcome. thanks
