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"

Vignette without post processing volume

To use post process volume on mobile it has to have HDR mode turned on, but it impacts performance a lot so i'm trying to find way to add vignette without that volume.

I tried adding image to widget blueprint but its completely black. Is there any other way?

There are second way to add vignette. It's to add a semitransparent frame mesh around the border with gradient texture on it.

  • Material domain: Surface

  • Blend: Modulate

  • Shading: Unlit

  • Render After DOF: unchecked

I really recommend you to make a polygon around screen to minimize the overdraw.

You also may use UI domain and add this material as a widget (I guess this may be a proper way).

Here. Made an example vignette mesh (file in attachment, FBX not allowed, so it's in ZIP).

And this is how it looks when radius and density is set properly: alt text
