Weight Painting on bodies rant

[Kentum]

Excuse me but I need to rant about this: The weight painting on (haven't checked males but I think it has the same problem) female bodies sucks. The pelvis is not a bone but a zone to begin with, a zone that gets affected by the movement of the thighs and the spine (I know it actually means the hips). The genital area should rotate with the spine and it doesn't because people who did the weight painting on the bodies don't know how the human body works. it is as easy as looking at a contortionist to realize that as one bends down, the genital area rotates backward, as well as when you bend your spine backward your genitals or your pelvis rotates "forward". It is not really something to blame the animators because it could easily be solved if the weight painting in the pelvis was done right.

The last couple hours I've been tryng to fix this in outfit studio but I don't really know what I am doing and I get spikes everywhere, I know I should export the file to a better editor and work it there but I would be double as lost, and it comes down to one of my life philosophies: If you are going to do something, do it right.

 

Some sex positions are literally impossible to animate since the weight painting of the bones is just not right. Doggystyle animations for example have this problem, the genitals never align.

 

The image I attached shows an animation where it is impossible to align the genitals by moving the characters the reason why is the vagina should protrude backward as the woman is bent forward.

 

If you are ever going to work on something do some research at least.

 

Rant over, I am sorry, please don't take this as an attack or something this is how I express myself, I am not trying to cause problems or anything like that. If I am wrong I am all eyes to read you.

Fucking right? Christ…

ETA: that quote didn’t work, but nonetheless. I’d say, if you’re gonna complain about something, read and research. Since the OP is so knowledgeable, fucking fix it.

Well at least you ranted. Move along, then.

The weight painting isn't the problem.  The problems come from the .nif (NetImmerse File) format and Bethesda's 25 year old engine.  It can't handle enough bone indices or bone weights per vertex to provide better/smoother animation due to bugs, crashing, performance and core engine limitations.  Blaming the animators or those painting weights on the bodies only illustrates the lack of technical understanding you have for this topic.  This game is ancient, built on obsolete game tech and was never designed to render convincing sex animations.  The animators that continue to produce such animations are doing the best they can with what they have to work with.
