Err.
It could be worse. It's not unrealistic, as such. I used my (still WIP) improved male fat morph as a guide so it wasn't nearly so... so. You know what I mean. But this is just not doing it for me as a fat morph for a very slender, lightly built man; it's not believably 'eats a lot and is a couch potato' for someone of that shape, it's 'been bedridden for months' and/or 'is on medication that causes weight gain'.
So, I have a workaround in mind, although it's very, very kludgy and involves deliberately mis-commenting the fat morph on tops to override the bottom morph. See, if you miscomment a morph--like, commenting a top 'botmorphs fatbot'--then that morph will change when the body state changes, but the comment will override the morph on the bottom.
Theoretically, anyhow. That's how it worked for HP's shirt mesh and the pregmorph. I'm hoping it will apply consistently so I can use that to force the regular morph bottoms when male androgyny tops get fat, so they can have appropriate couch potato pudge. Otherwise, the option is to make completely new bottoms, and I'm looking forward to that about as much as I would to a root canal. :|
ETA: I'm having One of Those Days where I can't stop nitpicking my work to death, thus rendering my opinions suspect, so here are some ( comparison pictures. )
