Lung models at various stages of development.
Model Progress
I reused a lot of my lung assets from my Unity interactive from late last year, so the lung modelling went smoothly. I added an extra lung between the pre-cannicular and saccular we saw in the interactive, and then mocked up what the “squished” lung would look like when the fetus is suffering from LUTO.

Retopology
I retopologized all six of my fetus models, so they now all share the same skin. This will be advantageous later, as I’ll be able to reuse UVs, bones, and animations.
I used ZWrap (R3DS), and was delighted how smoothly it went. For some of the more dramatic changes (the bladder, for example), I had to do some more work, but for the fetuses – which are the sculpts I’m more precious about – there were no issues.
