Cesium improvement as it is done in D5

Hello to all colleagues and to staf D5.
How to solve and improve the quality of Cesium in D5?
I would like to know for a placement of one of my works, perhaps there is a solution through D5, or first something must be done on the Cesium site.
I hope there is something, without using AI, but the quality of both the Faces and the images inserted in these polygons.
I know for sure with the increase of polygons or faces I increase the management of the file, or there is the possibility of having the Point Cloud, perhaps it would improve the quality!
