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"

Image distortion in UE4

Alright so, I'm gonna have a hard time explaining this. I want to know if there's a way to distort an image, decal, or sprite, or a group of them.

I'll use this mock HUD I totally didn't copy directly off of ShooterGame as an example by applying a "curve bend" distortion to it in GIMP.

Here it is normally: alt text

And here it is with the curve bend: alt text

Is there any way to do distortions like such in UE4? More specifically, if possible, to a HUD? If not, I highly suggest this as a feature.

Product Version: UE 4.8

Hi ViddyXD -

In fact this is entirely possible in the Editor now. All you would need to do is set up some UV math using Cylindrical UVs and a world aligned texture so that all you pieces on the HUD distort based on their location on the screen. The tricky part would be the math conversion from World to Screen Space without unwanted distortion.

Thank You -
