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"

Black lighting (UVs exist)

I have some very strange behaviour in the FPV example map. When I move my assets up too much they turn black! in the screenshot I also turned off the directional light. It is all there in the lightmap importance volume and the assets have a lightmap UV. It is the same with lightmap and without lightmap rendering.

Any ideas?

have you checked your volume light samples, show->visualize->volume light samples. See if there are any or if they are not black?

Hello Davision,

There are a few reasons this could be happening. You mentioned you turned off your Directional Light? Do you have any other lights in your scene that are illuminating these objects? If you have disable/deleted this light after building your scene and you attempt to move these object, because they no longer have a light source to illuminate them, they are turning black.

Also the meshes in your scene you are moving around, do they have lightmapping UV's correctly applied to them?

Thanks,

Andrew Hurley

No both things were not the case. When I have the directional light on those black pieces were grey lit, darker lit. I could not figure out where that other light is coming from, there were no light sources left. I ended up making a new blank level and have not encountered it again.

Ok I am glad at least you were able to resolve the issue in some way. If you encounter this again, let us know and we can continue to investigate.
