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"

Making a flashlight. Blinding light when standing near a surface.

alt text

On this screenshot I have a flashlight setup - a spot light source with intensity 100 and attenuation radius of 2000. Is there any way to make it not being so blindingly bright when standing next to a surface? I mean, sure I could just lower the intensity, but then it won't illuminate anything further than couple meters.

So far the only thing I could think of is making it toggle between long-range light and short-range light like some flashlights do irl.

But I'm more curious about other solutions to this problem, if anyone has any ideas.

You have two options.

1) Use a ray trace. If it hits a target, calculate the distance and lerp the intensity relative to that distance.

2) Use a light function. https://docs.unrealengine.com/latest/INT/Engine/Rendering/LightingAndShadows/LightFunctions/

I'm not exactly sure how light function would help in that particular situation... I'm not really familiar with it's capabilities.

But thanks for the advice regardless! I'll look into it.
