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"

Shadows Appear Differently in Blueprint Virtual Reality Project

Hi all,

I've setup a new Virtual Reality blueprint project (which works awesome right out of the box, by the way) and I'm having an issue with shadows/lighting. After much digging, my issue appears to be something to do with the project type itself. I setup the exact same scene in a new blank blueprint project, and the issue does not occur. Both projects have the same exact post proc settings, and light source settings. I even copied over the rendering portion of the project settings from the blank project to the VR project. Is this a bug, a setting that can't be changed in VR blueprint projects, or am I still overlooking some settings somewhere? Thanks for you help!

And here's the shadows from our VR project (what needs fixing) alt text

Hello iamshaneihaveaface,

When you say that you this only occurs in your VR project, did you create that project from the VR template?

Yes, I did. I created a workaround for this by creating a new blank project, and then just copying all the assets/blueprints from my VR template project. Although the issue is basically resolved for me, I'm still curious as to what the cause of the original problem was in the VR template project.

With the information provided I believe this is working as intended. It appears that the issue deals with ambient occlusion. This is what you are seeing with the shadows in the rafters. However, "r.AmbientOcclusionLevels" is set to zero in for the VR template. This can be found in the Default engine ini. I have provided a link to the documentation below. I hope that this information helps.

Make it a great day
