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"

Simulating physics on multiple bodies breaks PHaT

Hello, I am currently creating a model that has dynamic hair and tried to use the PHaT to get that result. When I set "simulated physics" to a chain of joints it works fine.alt text

But, when applied to multiple joint chains, I get this result. alt text alt text

Now, let me explain the way I approached this.

I gave the roots of the chain a physics assets and set it to default., the rest of the chain is simulated. But once I did the same process to another set of bones that was higher up on the bone hierarchy, all the bones that were simulating physics that were below that set of joints on the hierarchy started zeroing out inside the head. The chain that was highest on the hierarchy list would work fine.

The head does have a physics assets in it for collision of the hair, but with or without it I get the same result. I would really appreciate some assistance on this because I've been trying to figure it out for a few days now.
