I decided to try something really ambitious to see if the Instant Meshes program could handle it. I found the complete OBJ model for the Cafe LeBlanc model from the Persona 5 video game from Sega. The model was broken up into parts, with the main modules being 4 meg and 8 meg. I loaded the 4 meg one 'as is' into the Instant Mesh program and set the count to 8.57 which I thought was enough to capture most of the detail. It turned out that most of the model segments were in some form of a grid, so it did a pretty complete job of building quads, but with a lot of the model segments being overly detailed. I only used the 'align' button to set it up.
I then imported the rebuilt OBJ into A:M and spent about an hour mostly getting rid of excess detail in the imported model pieces. Then I did the same for the 8 meg file. It turned out that the 4 meg file was mostly the structure of the buildings and the 8 meg model was the props, and outside structures, etc.
The decals were also included in the download so I applied a few just to see if it was going to be easy.
Overall, I spent about 2 hours on the project to get it to the present state.
Attached are 3 pictures and a short demo video. The first picture shows the original OBJ, the second was the OBJ generated from Instant Meshes and the third one is the Hash model after I cleaned up the Instant Mesh version and added props from the 8 meg file. The video is a walk thru inside the model so I could see where to continue to refine it.
