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"

Batch Export doesn't export everything

So I need to resize several hundred textures so they are powers of 2. I selected them all, right clicked, chose Batch Export, and let it go, but with 872 files selected, there were only 805 exported textures. I don't have the time to export them all one at a time, so can someone clue me in to why this is happening?

I'm having the same problem with exporting single texture files. A lot of them just fail to export no matter what. If you need a sample asset for testing this behavior, Rock_Free_FloorBrown01_Albedo.uasset from "Luos's FREE Modular Caves/Rocks mini Package" (found in the Community Content section of the forums) was one of such files.

Another related to exports issue is that there seems to be an image dimension limit for exporting at least some file types.The HDR cube map (KimsBackYard.uasset) from recent Open World Demo Collection is a 10,000 x 5,000 texture asset. But it only saves as a 4096x2048 HDR file on export. It may just as well be intentional, but without any warnings about reduced texture resolution it definitely may cause problems for some people, so I thought I'd mention it as well.

EDIT: Forgot to mention the version: 4.7.5.

Hey robosaur -

Since the engine will export as a 8 bit Channel TGA file format, if any of your files were imported as a 16 bit Channel PNG, the engine cannot export those image files. Unfortunately there is currently no way to tell which of those images are imported in that fashion except that they will not export even if done individually.

I have entered a report for this issue, for reference UE-11869, I will let you know of any developments as we continue an investigation to a solution.

Thank you for your report -

Eric Ketchum

Does anyone have an alternative solution to exporting them while waiting for a bug fix?
