Where can I learn more about using the additional Containers like FTexture2DResourceMem or TAlignedBytes? I’m trying to figure out how to take an array of bytes (containing image data) from an external library and expose it to Blueprints. Seems like one of these might be what I want but I can’t find any documentation or examples on how to use them.

If you searching examples of use why dont you search in engine source code? 😉

I did but couldn’t find any. If you have a link to a line in the source that would be really helpful, thanks!
