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"

How to offset the location of a single bone, without it detaching from the mesh? (Pictures included:)

I'm making a ledge hanging animation. I want the character's hands to adjust their position based on the the angle of the ledge he's hanging from. This is what I made so far: alt text

I can successfully set the hands to the proper location, the problem is that it becomes detached from the arm, which I don't want. This is the anim blueprint I used: alt text

(Note: Never mind that right now the position is "fixed", I'm eventually going to use traces to find the exact location to set the hands to, but I already know how to do that.)

Am I on the right track here? I'm pretty sure in order to achieve the desired look, I'll need to use a ragdoll, or a physics anim blend, is that correct? (Please note: I have decent experience setting up both of those.)

How can I set the locations of the hands, without breaking them apart from the rest of the mesh? I want the entire mesh to adjust. (Much like in this video: https://youtu.be/fMxYY1z9k8k?t=153 (Watch it at 2:33.))

I will be happy to receive even a vague answer. :) If you've got the slightest idea of what I need to do, don't hesitate to tell me.

Did I explain everything okay? I will be happy to give additional information if you want.

Remember that I don't need a step-by-step guide, I just need to know where I need to get started. :)

After scrambling through the internet for days, it turns out what I needed was a two bone IK. (For each arm.)

If you want to learn more on IKs, here's the official documentation on IK setup: https://docs.unrealengine.com/latest/INT/Engine/Animation/IKSetups/

However, for some reason the document dose not tell you everything you need to know. (Which is very annoying.) Unfortunately, in order to "fill in the blanks", I think the best thing you can do is download the content examples map and take a look around: https://answers.unrealengine.com/questions/202293/how-do-i-download-content-examples.html
