Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Ragdoll & Collision Capsule

I am trying to go from Animation to ragdoll, back to animation.

I have no problem getting a character to ragdoll by simulating physics on either the root of the skeleton or the pelvis. Unfortunately, if I simulate physics on just the pelvis, the collision capsule will cause the skeletal mesh to hover in mid air.

If I simulate physics on the collision capsule, and simulate physics on the pelvis, the collision capsule rolls around and the skeletal mesh inherits the rotation and velocity of the capsule. It looks like the mesh is caught in a blender.

If I simulate on the root bone, the skeletal mesh appears to detach from the collision capsule. This actually acts like a proper ragdoll. Unfortunately, this means that the two components are detached, and when I stop simulating physics, I have control of the collision capsule, but not the skeletal mesh. The mesh reacts to inputs and displays the proper animations, but is stationary.

Does anyone have any experience with this?

Bumping up... I am researching this as well. Based on some older posts it seems that there was a time where, if you simulate bones below the root, capsule and mesh would stay attached. But now they seem to be getting detached... How can we keep these two attached while using ragdoll on the mesh

hi) solution is: attach mesh back to capsule component and turn off simulate physic for mesh. need tweak but works) alt text

this is far from sufficient, at least for me, you're deactivating the ragdoll to be able to have proper capsule component again. I wanted to use collision during ragdoll mode. I'm guessing the actual answer would be something like: - updating the capsule component location to the location of the mesh each tick, or - using the mesh itself (or maybe attach some collision objects to it) to detect collision

Or just use ragdoll when you're done with the character in game of course.
