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"

Duplicating a Blueprint in the scene spawns a different Blueprint with the same name

I have a series of level tiles in different level folders which, for consistency, are all named the same. For example, TILE_FLOOR, TILE_DOOR, TILE_WALL_STRAIGHT and so on.

The problem I'm having, when building a level out of the tiles, is that duplicating a tile (for example, when creating a long wall) actually spawns the same tile but from a different level folder - in this case, its spawning the equivalent tile type from the first folder set. I'm assuming here that Unreal finds and creates the first instance of the matching tile. I hope this makes sense. Just to be sure, here are a few images illustrating the problem:

Step 1: I place a door tile from LAYER_1 alt text

Step 2: I duplicate the Blueprint (Alt + Drag)

Step 3: The resulting duplicated BP is not the one I wanted alt text

The tile I receive after duplicating is the equivalent Door tile but from the very first folder set of tiles (LAYER_0), and the same effect happens when duplicating the other tile types.

Should I submit a bug report for this? alt text alt text

Anyone have any idea?

Hi there, I had this too now but it took me a while to realize that it was just because of the name and not because of some copy reference when reproducing it, and there is even a warning log message for that ^^ I posted my bug report here: https://answers.unrealengine.com/questions/386613/duplicating-assets-in-level-just-uses-the-first-as.html

As a good practice, you shouldn't give two different assets the same name, regardless of folder structure. Not only do you increase your chance for bugs, but it's also hard to manage in version control, searches and so on.
