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"

There is not enough information in that error, and it may be caused by many things.

Can you add some description about lightning you use?

I only use the standard light setup in the empty template: Skylight and a directional light. I don't really know where to get more information, that's the only error it seems to be giving me.

So you just created new map from template, build light in it and get this error?

I used this template: https://gyazo.com/57617b449da26027bdd894583bd3d96c and made this: https://gyazo.com/bf1b21bbd8d17fa440351fbd6ad80a0b I could build the light in the start, but I don't know what happened to make it so I can't build the light anymore.

When lightning build finished, it creates asset "map_BuildData", and stores lightning information inside it. Maybe you accidentially delete it?

that could be it, can I readd it?

avatar image redbox May 10 '17 at 10:44 AM

It will be added after next lightning build

But that's what I am trying to do, and this is the error I get everytime: https://gyazo.com/bf1749272ed617dab678ff82657a6d6e
