How to smooth extremely dense mesh? I have an imported model (which actually is a surface projection of an microscope Z-stack image, exported as STL) which is extremely grainy, composed of almost 1M verts. Is there any way to reduce number of verts/faces and smooth it to recover the general cell shape? I tried smooth and remesh modifiers, but it didn't help a lot :( 
Thanks for any ideas!

Try scaling it on the Z axis to 0 in edit mode to get rid of all the bumps if thats what you are asking.
