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"

Just to clarify, here's how you set the "Add Spline Mesh Component" node to add a moveable static mesh (pardon the oxymoron):

You gotta click the node to highlight it, then check your details panel, and change the mobility in there.

Hi Davision,

It will actually work at runtime but you will need to set it to Movable.

This is actually by design. You can set the mesh with a Construction Script even on a Static component, but not during runtime code like BeginPlay. This is because the StaticMesh is just that, static and for it to work at Runtime it will need to be set to Movable.

Ok, that makes sense. I keep missing that some nodes have a details setup. Would be a nice change that the default setting would be Movable when placed in a event graph since with the default setting Static it is useless.

Ugh, got caught up by this as well and spent a good hour trying to figure out why it wasn't working. Setting the mesh to movable indeed solved the issue.

What still doesn't seem to be working though is assigning a material at runtime to this mesh with SetMaterial. The mesh keeps rendering with the default grey checker pattern. Any idea what to do there?

Edit: Never mind, just found out here that materials need to be explicitly enabled for use with spline meshes. Therefore this is now working as well.
