Sorry if I'm spamming this thread but I'm just so excited every time I manage to add a new part to my first working scratch Jbeam, I'm working on the legs now, trying to get them to move like human legs and so far it's looking promising

 

Added bottom leg parts, they can obviously bend to an extent like human legs, though the limitations here are bigger than on human legs because otherwise there would be visual clipping


Also, it looks like the dummy wanted to demonstrate its flexibility to you because it did this on spawn now and doesn't want to fall over lol

 

IT'S STANDING! Until you hit the Break All Hinges button (the beams that make it stand are latches and it breaks them).

They are pretty flexible because I couldn't make them any stiffer, more beamspring = explosion and more beamdamp = weird glitches. There are multiple reasons: I had to use refnodes from the left foot nodes so the Jbeam had to be cube-shaped in that area of the foot, and the feet collision has to be big to increase the area that touches the ground for more stability (the feet also have more friction than the rest, but realistically, I based the friction coef values on the Pigeon because it's also made of plastic).

Kinda but it falls over after 2 seconds lol

Edit: Arms mostly done aside from the hands that I can imagine will be a nightmare to Jbeam because of the fingers


Also, here's a stability comparison. I adjusted deformLimitExpansion for each part of my dummy to prevent them from getting messed up after impact. Here's the old dummy prop mod vs my dummy, both after 250 km/h impact:

 

All body parts done. Hands were a pain as I imagined, I ended up using non-collidable triangles for fingers to avoid triangle clipping because that causes a lot of random forces and I want to keep the Jbeam clean from that. The original dummy has a lot of beam stress issues and mine has none, the only "weird" forces are caused by the "muscles" in the knees that are parts of the "stand latches" system, idk what to do with them and they are small anyway and similar ones exist in vanilla content too. Movement is as realistic as I could get on all body parts. I think it's time to add some LUA now...

(I just noticed something is wrong with the weight distribution though, I need to fix it before I get to the LUA)
