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"

Hairworks and Alembic Caches. Hair not following.


I've managed to get HairWorks working inside of UE4 with a simple, skinned cube with one joint and 8 guide curves. For the next step, I wanted to create an Alembic Cache of the animated cube, and apply the hair to the cache inside of the Unreal Engine.

I was able to import the Alembic Cache using the Alembic Importer as a Skeletal mesh, and I see the cube playing the animation. I created an Actor blueprint, stuck in the Skeletal mesh, and attached a HairWorks component along with the correct .apx file.

However, the fur doesn't follow the animated cube. The fur remains in its original position. Is there a way to get Alembic Caches to cooperate with HairWorks? This would be ideal for us because our rigs are fairly complex, and using caches to bring in our animations simplifies the process quite a bit. We'd like to get hair on the character and also have it follow the geometry accordingly.

Are there any steps we can take to get HairWorks to work with Alembic Caches?

Thanks in advance, Vincent

Hi Vincent

Did you have any luck getting this to work?

Hi Moley,

Unfortunately not. Maybe it'll be something we try again at a later date...

Hi Vincent

Thanks for getting back to me.

I'm going to give gFur a try.
