Question about adobe illustrator. About the edges of the figures. I need your help. How to smooth the edges of shapes?

Question

Adobe Illustrator

For the background on the site, a background was created in illustrator, consisting of many svg polygons. The question is how to remove ladders on the edges of some shapes. They cut the eye and it's not the case at all. On the site, this whole thing should be in the SVG, since there will be interaction with each figure.
I will attach a screenshot

Answer 1

Lay a dark background down.

Answer 2

as a solution to the problem

Answer 3

As an option: score and try this graphics in action. Perhaps the final product will simply not have a ladder. The chandelier just renders in a somewhat specific way. Where does this background go?
