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"

Light Source in Virtual Reality causing Darkness in 1 lens only


I'm working on a Virtual Reality project and I'm having an issue that seemingly is coming from the Light Source from my level. When I put on my Oculus Rift headset, looking towards the light source (or the sun in this case) it looks normal, and looking away from the sun directly behind me also looks normal. However, I have this strange visual effect that occurs that is very annoying when looking around the level on either side of the sun. The effect that occurs within the headset is that the left eye lens is normal lighting, while the right eye lens becomes exceptionally darker and vice versa when looking the opposite way. I'll post a picture of what I mean.

How it looks like looking towards the light source with a VR headset on:


How it looks like looking towards the side with a VR headset on (Light Source on left hand side):


The effect this occur mimics the feeling as if you're loosing eye sight in one of your eyes depending on which side is closest to the light source. Is there a way to make it so that the light doesn't so drastically decrease in one eye and feels more natural? Does anyone have a way to solve this problem?

Solved the problem. The issue was caused by the 'Light Source' within the level. In the details panel of the Light Source, there is an option to adjust the Light Shafts. The 'Occlusion Mass Darkness' has to be set to a higher value in order to avoid either of the lenses to darken when in VR. This of course effects how the "god rays" look in the level. The reach around behind THAT problem is to check box enable "Light Shaft Bloom". This will of course make your god rays work a little differently, but I suppose for VR right now, that's the best method you can make without physically making the god rays.
