I've googled around looking for a way to do this but can't find exactly what I'm looking for.
I am importing a model from reality capture (photogrammetry), the model has a very low poly back side (from the mesh being closed by reality capture) and a high poly front side. I wanted to cut some holes in the mesh to tidy up the iron section on the top. But that didn't seem to work very well as the back was only being cut sometimes. Some googling suggested I needed a higher poly count on the back. So I subdivided (twice) the back in the sculpt (surface) room and tried again and I was able to cut properly. See attached images for front, back and back subdivided.
The only issue is I don't want to smooth when I subdivide the back. But the only way I have found to do a flat subdivide is when importing, but that does the whole mesh which bumps the poly count by a huge amount at the front which I don't want or need.
So is there anway to do a flat subdivide to a specific area of a surface mode mesh?
Thanks.
