Hi all, hope all is going well with the competition so far! 
We’ve updated the crab asset above with some minor tweaks. Use the same download link.
Giving this thread some spotlight in case anyone else experiences the 100 frame limit even after running the above getting started script.
Pushing another update to the crab rig with 3 changes, see the same link above.
For stiffness, check this out!
Super strong. These are stiffness values between 0.01 → 1.0. (No more values approaching 100,000 and beyond)
For pins, you should also find that values less than 100 to be a reasonable max for a very hard pin, as opposed to 100,000 and beyond).
Also rearranged the groups for a little less complexity; you can now edit all feet from a single group (as opposed to 1 group per foot, 8 in total).
For your own reference, here are some notes on how these things were made possible.
In both feet and tips, it was a problem of mass. The tips are especially damning, as they are tiny tiny tiny. Ragdoll would treat these as any other part of the crab, and compute a mass relative its size. Because it is so small, it would get a very small mass.
You might wonder what mass has got to do with anything. We aren’t interested in them weighing down on the foot, and it doesn’t seem related to stiffness? 
But! Such is life. Ragdoll is all about forces, and any force is relative the mass upon which it acts. Between the tip and the last joint of the crab foot is a force keeping them together, and when one of them is heavy and the other light, the more complicated it gets for Ragdoll to keep them together, hence values that reach into the thousands.
For the legs, I took a slightly different route. I didn’t want the feet to appear more heavy - especially not heavier than the body. So instead editing its mass, it now has a slightly edited Rotate Mass.
This attribute is mostly unexplored, so I’m curious what you think of this and whether you run into anything odd. Things to look out for is any strangeness in the rotation of any part of a leg. As if it’s resisting rotation, almost like Air Density on the solver.
Are there textures for the crab?
Hi Emi,
Just A ramp texture nothing custom. you’re welcome to texture or develop the crab further if you like.

Linking some more issues to here in case they happen to someone else.
Just a heads up that next week is the final week of this challenge!
So far, we’ve got more prizes than submissions, so everyone who has participated is getting something. 
The only question is who gets the grand prize of Ragdoll Unlimited and the also-great prize of Ragdoll Complete.
You can find all current submissions here:
new submission coming up this week ! finally had some time and head to come up with an idea !
stay tune !
Only a handful of days remaining (until Sunday!) 
On top of that, we’re having trouble with the licence server… Will keep you updated here. 
really waiting license, can’t work without it
I wasn’t able to narrow down what happened, it’s end of day on my end so here’s an alternative that will last you until the end of the competition.
4XGR-M4QV-6VPG-EZ94-Q26X-G8TX-QNTAHere’s how to use it.
It will say “Trial Version”, but is fully unlimited. Let me know if there are any issues.
thank’s will try right away
Licence server is back up. 
You can keep using the temporary licence key above, they’ll both work until Sunday!
Hello everyone!
Great work with this July Challenge, lots and lots of really good submissions!
You’ve still got a number of hours to go - we said to run until July 31 and for some that means the day has just begun. 
This is one of the places on earth where July 31 ends last, so let’s use that as our exit. Once the day is over for everyone on earth, here’s what will happen next.
There is a lot of prizes to give. 
For next week, 3 things will happen!
From tomorrow, Agora is arranging for a competition via their Discord.
The details are still being worked out, but I expect we’ll spin up another forum category here and post WIPs and questions like we’ve been doing for this competition.
Expect another thread to appear shortly.
That’s it! Go go go! 
2 hours and 50 minutes remain! 
Pencils down! Fabulous work everyone!
Stay tuned in this thread for what happens next. I expect prizes to be handed out before end of this week!
Gathering all submissions into one big video, have a look and let me know if I missed any!
There were a few submissions made without any video, these are not included. But if you have one, and can’t find it in this video, let us know in this thread!
It is great to see all those pieces !!! Lots of creativity"
Long life to RagDoll !!!
Hi everyone! The time has come!

These were the toughest ones! They are all magnificent! The Cheese Rolling Race is a great example of art directing physics; getting the cheese to end up at a specific location, and then transitioning the crab into a specific keyframed animation. Do not mess with my tail does a great job combining Locomotion with character-to-character interaction and Coastal Hazard has great comedic timing along with interaction with the environment; and a self-walking custom-rigged character! Crabtapult involves multiple crabs, touching on the effectiveness of physics to achieve slight variations in output from the same input and finally Hooked does a great job at combining Locotmotion (or is it?! 
) with traditional keyframes and physics!
And finally… 
The winner of the Unlimited licence of Ragdoll Dynamics July 2022 Ragdoll Challenge is…!

Round of applause! This one is amazing, utilising many of Ragdoll’s strengths, just about every feature mixed together in a big jug of creativity.
Well done!!
Huge thanks to everyone who participated! This went well beyond our expectations. You will all be receiving a private message here on the forums with your unique serial number shortly, followed by a more official email once we’re returned from the upcoming hectic next week in Vancouver.
If you want more, there’s an August Challenge happening with more prizes, more details here.
And if you’re in or around Vancouver next week, let us know if you’d like to stop by! We’ve got about 5 exhibition guest tickets we’re happy to give away if you’re up for some SIGGRAPH!
