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"

Hey JayC3D,

Could you provide me with screenshots of your Skylight actor itself, and have you made sure your lighting has been built between changing those settings?

You will also want to use the 'Recapture' option, which is located within the actor itself.

Let me know if you need further assistance.

Thank you,

Andrew Hurley

Hi Andrew! Here is the actor in scene...

I've already tried to recapture the scene and rebuilt lights...

Sorry I should have clarified. I meant the details panel of your Skylight. This could also be a Post Processing issue with Auto-Exposure. Try setting your Min and Max brightness to 1.0 within your post processing settings to see if that has an effect as well.

So are you attempting to use a specified cubemap, or are you attempting to use the captured scene?

Try setting it to Movable to see if that helps.

In fact, I tried to capture the scene... It works well in the viewport but in PIE it disappears... So I made a cubemap of my environment to verify if it works with a specified cubemap and it works well, no problem with this mode but I'like to use the captured version.... Here, on my screenshot, the settings are the same in both mode... :p (I'll try to make the Skylight movable next Monday, but I think it will slows down perfs in VR)

Movable might alter your performance, but if you just need the ambient fill light and your scene is fully dynamic already, you can disable static and dynamic shadow casting from the Skylight and use strictly the AO value. This will actually increase your performance.

Using a Skylight is all about balancing your ambient fill light and shadows. I have found that in darkly lit areas with a Skylight casting shadows it can be too much in certain cases.
