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"

Spawned Component is not blocking SM Actors

Hey Guys,

i made a BP for creating procedural rooftops to be placed in a level. Everything works fine but i have a little problem.

When building levels i want to place for eg crates or other stuff on my rooftops. So i place them in the editor and hit "END" to put them on the floor. Now there it seems that the spawned components in my BP dont have a collision and the actor i want to put on the floor is set to the next SM Actor below and not on top of my rooftop. Every other collision, especially when playing works fine and is blocking correctly.

Any ideas? (I spawn them with Add StaticMesh Node).

THX in advance.

Its hard to get enough information from the pictures even though it may seem stupid but do the spawned actors have a collision component? and is it configured correctly to interact with the boxes? also is it singleplayer / no dedicated server activated?

Do i have to spawn them a collision too? Because if i walk on the surface i spawn it works. But things like the crate in the picture wont align automaticly with the surface of the spawned compontent but with the static mesh beneath,... (when hitting END key).

Then I would look further on the collision channels maybe your roof only blocks pawns like your character but no static meshes. alt text

If the collision of the mesh is similar to this your box shouldn't fall through.

it is set to that. When you hit play no mesh of any kind will fall through. Its only in the Editor when you drop something in and hit END key.

I even set "block all" again in the BP for every component spawned, but nothing happens. Can someone reprodruce it with 4.6?
