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"

[Request] Bulk Renaming

I am working with Sprite Sheets at the moment and have begun to find it tedious to have to manually select each sprite to rename it for readability purposes. For example, each frame of a birds flight flipbook animation "Bird_Flying_001, Bird_Flying_002, Bird_Flying_003", etc.

Could it be an idea to begin to include a bulk renaming system? I mean such as to select multiple items, rename them (So for this example "Bird_Flying_"), then have the engine assign a number for each of them, beginning at 001.

I feel it would make the 2D workflow generally a bit faster, and would also make other work less tedious. Any feedback would be welcome.

Anyone???? I've tried using the external program Bulk Rename Utility and it renames the asset files, but doesn't change the names in the Content Browser. I've got a ton of animations I'm trying to categorize by name and it's long and tedious work to do by hand. How does Epic themselves handle the bulk renaming of assets within the editor?????

This would be great.

Working on it from Blutility. I have several maps that are 343 levels in size and want them renamed for the map instead of just the generic Name_X#_Y#_Z#.

Will post if I get it working.

The key words there are World Outliner, which is the list of assets on the currently loaded map. I need to rename the actual assets in the Content Browser. MORT doesn't handle that, and I really wish it did. Just a simple command added to the context menu called Bulk Rename that allows you to add prefixes and suffixes to a set of files, and automatically calls Fix up redirectors when it finishes renaming them all.

Will try to make something for you (already have some results and they are really good). Now I need to combine everything in one place and update MORT.

Next version will support Content Browser and you can use function "Rename and Numerate" as you wish, so it will fix your issue. Just watch the youtube video of MORT 2

Amazing, you introduced this feature to me, and is extremely helpful. Now instead of looking for a plug in I made it my self. Thank you sir.
