After some problems I had with the 3D scan app I used before, I got my hands on another 3D scanning software, Agisoft PhotoScan, and tried some experiments with that. With this software, you can take panoramic photos of the object you want to capture using a camera, and then import them on the app to further edit them.
This program can give better scanning results, as you can control better and further edit what it perceives from the pictures. From my first tries, the results are quite improved than before, even though there is still distortion, which personally I don’t mind and think it adds up to the aesthetics.
So, using this software, I have started once again scanning body parts and then further edit them on Maya if needed. Depending on the results, I am planning to use some of the meshes for my final piece.
