Ragdoll issue with MassFX

Anonymous — Mon, 31 Aug 2015 16:18:23 GMT

Hello, I have an issue when I use a dynamic ragdoll modifier on a biped, I only have a plane as a floor and a standard biped with a dynamic ragdoll massfx modifier on it, and here's what happens when I hit play simulation on the MassFX toolbar... (good laugh guarenteed)

I don't remember having this problem in previous max versions...?

Some more informations that may be useful:

- This was done from an empty scene, in 3ds max 2016 expansion 1

- The biped is 180cm tall

- The plane is 5m x 5m with a MassFX Rigid Body set on Static (no other parameters modified)

- The "Use Ground Collisions" checkbox is unchecked

- Every other parameters are unmodified

Here's the .max file if anyone feels the envy to try to fix it

I haven't messed around with biped ragdoll yet but it looks like a lot of fun!

I did have a look at the file and it looks like your massfx collision meshes are overlapping each other. This is not good in gaming engines and would cause the behavior your seeing here. Not sure if this is true in your case but it is something to try.

Thanks but this is the standard settings, how can I undo the overlapping ?

Alright, I fixed it by reducing manually the collision capsules of the MassFX modifier for each bone, but it's strange that there's no global setting to set this...

Works quite good now, still some wiggles during static poses but that will do for now

Here's how the capsules look now:

And you'll find the .max file below

Glad it worked!

Scene looks fun and I am definitely going to poke around at this feature!
