Making a mobile device application might cause stricter restrictions on:
- file size >80MB + additional content, 5MB/texture, it'll be fairly heavy application. Think about the nightly builds.
- mobile phone devices have worse total computational performance than personal computers
- more compatibility issues
Not sure if it's worth it to be honest. Lots of effort just to create a Makehuman-lite (less powerful, less stunning, less useful).
I see no reason why would anyone go for the lite version of MH. Contrary I see plenty of people who would love to go for some kind of Makehuman-extra (extra physics, extra texture features, extra anything). So far there weren't many people asking for MH phone app anyway - please correct me if I'm wrong.
Thus going for new/better (or finishing the WIP) features might be better than just expanding into new devices.
