odf: Hi :)
The main problem with the rigging the crotch with a bike shorts type hip was the position of the crotch. The crotch sticks down and out and you want the legs buttocks to move with as little as possible of the crotch moving. next to impossible with poser rigging unless you do as is usually done and put the leg center down and below the problem area, which gives horrible looking leg and hip deformations.
I have had the same problem with Brad, even worse since his stuff really sticks out :) But recently I changed the grouping in the hip area to include a genital bone, and simply grouped a small portion of the hip covering most of the genital area, which does wonders for this problem. It allows you to grab much more of the inside leg with the red fallof zone and still keep the crotch in place. (of course there are problems with mesh pull away.)
Also I moved the crotch in towards the backbone and up towards the belly which also helps alot and from looking at grays anatomy of the human male I think it's closer to correct. I have not tried on a female figure yet, but I would think the same type of thing may solve most of these issues. But I dont know,have to consider that the genital on a female may not be correct if moved up..........
When I made the rig for Antonia I tried my best to do it without moving any geometry or changing the shape, Didn't feel it was my place to change the shape. So I let some of the inside leg bulge out somewhat instead of grabbing more of it and causing breaks. I believed at the time ( I still dont know) that it was important that JCM's remove volume rather than add volume for clothing, I am not sure this is correct.
Brad also has a wealth of poly's which gives me more leeway. Antonia bends very well in my oppinion, the JCM's you have made are expertly done. I dont see why any JCM's in the clothing cannot compensate for any movement of the underlying geometry. I would think that the JCM's in clothing are of course going to be different than the ones in the figure itself, maybe close, but they still must compensate for poke through, and shape etc. so they have to be different. Conforming clothing is basically it's own figure and need not have the exact same JCM's as the parent figure, is this not correct?
Well, just my .02
P.S. I also changed the rotation of the center of the legs which compensates for the lack of being able to use the Y rotation of the falloff zones this also has alot to do with getting a cleaner grab on the inside leg. Many people likely will not like that it also makes the leg rotate at somewhat of an angle. :) So prices to pay for anything done.
cheers,
Mike.
