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"

Uneven Illumination of dynamic object with spotlight

As you can see in the following picture, the characters beneath the spotlight get abnormal uneven amounts of light. http://puu.sh/cWO0f/e5a613d3aa.jpg

One step left Im dark, one step right I'm super bright. This shouldn't happen as I use a very large angle for the spotlight.

Here's the spotlight setup: http://puu.sh/cWOD3/09eeb1fa50.jpg

Note that the other spotlights arround are static so they don't affect dynamic objects.

What's going on? How can I fix this?

Problem solved: adding a missing lightmass importance volume allows UE to calculates the volume lighting samples properly. I did not know that and I'm happy to see it is not an issue!

Hi Bigzer,

I've not been able to reproduce this on my end. I used your setup for your spot light and only used stationary ones in my scene since static lights would not affect the character player anyway.

Here is my test setup:

I didn't see any sort of issue with the lighting giving similar results to what you're seeing.

Are you able to reproduce this in a scene other than your own project?

Thank you!

Tim

This is curious indeed, allow me to come back to you, I'll try to build a repro project for you to download.

Tim, I have found the culprit: A missing lightmass importance volume. I found it out when I tried to make the repro level for you and I did not have the issue even when I copy pasted the entire room from the other level. Thank you very much for looking into it, Epic's support is the best out there!
