You can use Femshep's Quarters if you want the space view. It fits under it with ease.
Technically the SR3 is the one used in Mass Effect 3.
Not every model has textures for every skin group, I added the option for people to add textures themselves.
I haven't encountered those issues yet with the props. However an easy fix is to drag the model into view using RootTransform and after that using other bones to move the model around and not touching RootTransform anymore. I do the same for rope models, since they always disappear.
PhoebusTheRisen, I checked all the flexes and they are all working correctly for me. I am not getting any of the issues you are having, so I have no idea why you are having these problems.
I have a working Aria model with eyeposing and everything clothed somewhere. I have a nude version up on my Patreon, but she still beta. Will have to upload clothed version on my Patreon as well.
Next time give me a heads up when you steal an almost finished project of mine.
