It not only makes your models complicated but also takes much longer time and a more complicated process to complete rendering.

Though VRay is an excellent and powerful rendering service you do not want to make your models with rough edges and incomplete format. To avoid this, it is important to be mindful of the number of edges in your model and optimize where necessary.

It can also cause slowdowns in system performance and render times. This can cause problems as the file becomes too large and unwieldy to work with. As designers, we often become so carried away with designing that we end up with a Sketchup file that is 300+ Megabytes and has over 2 Million edges, or at least that is the case with most of the beginners in SketchUp modeling.
