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"

Why is GPU particle collision not working with scene capture component?


For some reason, specifically when I put a scene capture in my character blueprint and assign that to a render target, the collision in the particles simply stops working... Any idea why?

Can you post a screenshot of the problem please? Also, does the collision not work when you look at the particles from the player's camera as well?

The same happends to me, im capturing an animation and a particle, when the player camera go to a certain distance away from them, the animation stops or the scene capture stops capturing. Im wondering if this is a Scene Capture issue or is something about distance from the particle system?

Hey Luke -

GPU Particle Collisions work by reading the Scene Depth and are based on the player's screen space, so if the scene capture actor is rendering a GPU effect that is happening outside of the player's view (the engine's ability to render scene depth) the particles do not know how to collide and will not.

Hopefully that clears that up for you. If you need any further help let me know.

Thank You

Eric Ketchum
