I'm a beginner in modeling and have been learning how to create a person basemesh in 3D. I just finished making the eyes of my person, and am about to begin the nose. However, my Blender has become extremely laggy. This was not a problem earlier until I had finished the eyes. My current file size is 7.7 MB.
I checked the computer resources, CPU utilization does not go over 22%, and memory utilization does not go over 45%. I am not sure what is causing the extreme lag. Any ideas or pointers would be highly appreciated.
