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 do I change the pivot of the VF Rotation Rate?

Hey all!

I've been going through the tutorial on the GPU emitter, but I'm having an issue on one spot. It seems the VF Rotation Rate module pivots from a point at the center of one of the faces of the box, rather than the center of the whole volume. Is there a way to fix this, and make it rotate is it does here: https://docs.unrealengine.com/latest/images/Engine/Rendering/ParticleSystems/Reference/Modules/VectorField/VFInitRotRate.gif

Many thanks!

Hi ianoreo -

Was this a custom created vector field or one from the engine? If it was custom created, where was the world origin of the VF? It looks like your World Origin of the imported Vector Field is not at the center of the field.

Thank You -

Eric Ketchum

Ah that was exactly it, Eric. Thanks so much! It was the only one bundled in the starter content, but I just exported a fresh one in Maya and the issue was gone. "VelocityGrid60" was the one I was using from the bundled content.
