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"

Can you specify a Texture size output per platform?

I see that under compression (texture content browser) there's a Maximum Texture Size...

Does it mean that even if I imported a 1024x1024 (raw file), but input say 512 in Maximum Texture Size that every platform will get 512x512 max? PC won't get 1024x1024 but 512?

  1. Is there a way to specify that I want 1024x1024 max on PC, 512x512 on PS4/X1, 256x256 on the N Switch and so on... for the same texture (uasset)? Basically let UE4 compress and assign the right texture size per platform that I wish to have?

  2. As well as seeing the preview directly in the engine?

  3. Is there a way to specify I want to have a Normal Map compression of DXT5 on PC but DXT5 half size on PS4 and DXT1 quarter size on N Switch?

  4. Controls such as this concept Texture Output Editor would be nice:

You can specify the maximum texture size per platform and texture group using the Device Profiles. The basic functionality is described here: https://docs.unrealengine.com/en-us/Platforms/DeviceProfiles

There is also an editor for this in the Editor under Window -> Developer Tools -> Device Profiles:

Your options only seems to limit texture based on platforms - for all textures.

I'm looking for an options to set specific texture sizes per platform:

Like WaterTexture_01 is 512x512 on PS4 but 256x256 on NSwitch while the Normal Map remains 512x512 on NSwitch. However WoodTexture_03 is 1024 on PS4 but is 2048 on PC while it is 256 on NSwitch.

Something like that...

Well there are multiple texture groups you can assign the textures to. For each group the maximum texture size can be set. Setting them individually per texture per platform will become very tedious very quickly, I personally see no real benefit in such detailed options.

Part of your example would be possible by lowering the Max Texture size of the World Texture group, which leaves the WorldNormalMap textures unchanged.
