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"

Changing the Brightness of the Scene/Camera based on a Variable


I'm currently attempting to make scene seem darker/lighter to the player based on a variable. I currently have the variable going into a Vignette Color/Intensity Post Processing effect, but that doesn't seem to be working as I want. I want the scene to be really light when 0 and really dark when 100.

Does anyone have an idea of how to do this?

Thanks! Ben

I'm not sure camera exposure is in post processing. As I'm sure you know auto exposure is for something different. You may have to turn the lights down instead- connect them all up to a timeline and go from 1 (bright) to 0 (dark) in the time you want. Effectively, it would be exactly the same.

Hi Robbie,

I've tried to do this, but I'm not too familiar with Timelines. I appear to have it working by having a cubemap attached to the camera and changing the intensity of it. Is this a bad way of doing it?

If it works, then no! if you want to learn about timelines at a later date, take a look at this https://wiki.unrealengine.com/Dynamic_Depth_of_Field, which shows a timeline hooked up to break and make post process effects, and this https://www.youtube.com/watch?v=6Vmo0E_hiFY which is part of a series on making a flickering light...
