I recently had the opportunity to purchase a copy of Manga Studio 5 at a steep discount. I had long been interested in the software after viewing a demo video and seeing the included 3D assets, which differed greatly from the assets included in Manga Studio 4.
After initial installation, I was surprised to find that I could not locate these assets. A little bit of research later, I discovered that installation of the included Materials (which includes the 3D assets) was a secondary step. I carried it out with haste.
That was when I noticed something odd. I use a SSD, so I installed Manga Studio 5 on a secondary drive. However, my C drive's space had decreased after the material installation. I had never been prompted for where to install the materials, and had naively assumed that they would be installed with the application. This was not the case. The files were placed in the C:\ProgramData\Smith Micro\Manga Studio\
