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"

Building lighting

Hi! I am new to Unreal Engine 4 and I read a little bit of the documentation and I have a question about building the light. If I build the lighting for some objects, let's say 10 objects, then I place another 20 objects, when I will build again the lighting will it build also the first 10 objects or just the 20 new ones? Thank you for spending your time reading this and I apologize for my English.

Yes, it will have to re-calculate the lighting. If you are have a static scene, build lights and then make modifications it will invalidate your previous light build and re-calculate lighting from your directional light, spotlights or pointlights when you built the lights again. However, if you are not creating a project where performance is the main priority you can try a dynamic lighting scene could work better for you, this removes the requirement for light maps and allows all lighting to be ran at real-time via the GPU.
