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"

Datasmith and Precomputed Lighting Scenarios together

Is there workflow to use both Datasmith and Precomputed Lighting Scenarios ? I use Sketchup for modelling my archviz project and then bring it into UE by Datasmith. I've seen couple of videos about Precomputed Lighting Scenarios and it looks like I want. Basically I want to have single model, but different lighting applied to it. I.e. I want to import model then go to night sublevel, tune some lightsources, bake lighting, then switch to day scene and so on. But I want all non-lighting actors in both sublevels to be in sync. I.e. if I apply material somewhere in day sublevel, will it be automatically applied in night sublevel? Or delete something, or add/move. Same with Datasmith: if I do some changes in my modelling app, will it propagate to all sublevels? I don't want to do double work, i.e. repeat same changes in both sublevels.

My current experience for this is very painful (as always with UE). I've created couple of sublevels: Day and Night, marked them as Lighting Scenarios, moved some stuff to Day (skylight, directional, couple of rectlights). After that I tried to re-import Datasmith file: everything flickering. I check Outliner and see EVERYTHING duplicated. I try to re-import again and see EVERYTHING duplicated again :(
