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"

Hello svv3dUDN, I have tried this in both 4.7.3 and 4.7.4 and that doesnt work. I thought I made a bugreport about it for 4.7.3 but cant find it.

It works fine for 1024/1024 textures, 2048/2048 textures, but not 4096/4096 textures. (havent tried 8192/8192)

Edit: 8192 also works. O_o Edit2: it seems to be a bit more convoluted than I innitially thought. Will try to find the source of the problem and report in a new post. (unless you are fine with me posting it here)

I imported texture 4096x4096. Delete source file. Save and reload project. Export texture. No problem. Texture exported normally. UE 4.7.4.

I found the issue, it wasnt the filesize but the filetype. 16-bit .PNG doesnt export from ue4. Not only that, but on import the texture is washed out.

Edit: updated the bugreport post.

I think the engine is having quite a bit of issues with 16 bit images https://answers.unrealengine.com/questions/493688/ue4-fail-to-properly-export-texture.html

Hey guys, So I discovered a work around of sorts for this issue. When you export the texture, it gives you the warning but it still outputs a TGA file for you. If you open the file in Photoshop (or whatever image editor) you'll see that it looks wrong. What's happening (at least in my case) is that it has inverted the color channels. So Green is fine but Red and Blue were flipped. You can fix this easily enough by copy and pasting the channels to their correct spot in a new document. So the Red channel is actually the Blue and the Blue channel is actually the Red.

Here's a screenshot of my normal map that was exported. The left is how it looked when I opened it up after getting the warning message and the right is after I swapped the Red and Blue channels.
