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"

How do I use the lightmap density view mode to my advantage?

I am new to unreal. I was watching someone in a tutorial who opened up the lightmap density view mode and mentioned how the colors on the level he had opened looked bad but he did not go into detail about it. What do the colors mean? Should I be trying to make each object the same color? Could you do this by changing the lightmap resolution on the objects individually? Thank you

Hello, I am not an pro about this, but For my ArchViz project I didt the follow: You Have to know that by making the Density Higher the Shadows get Better on those parts. Also what is written in UE Wiki about LightMap Density is that You should have an similar density on All object's. 1.Play Around with the Lightmap Resolution of an small part of your meshes Till you Get an Result (After Building Light's) that is good enough for you, and wich You like to work with. 2.Tweak the LighDensity In your ViewPort Light settings so that those Meshes you changed are most in the green Zone. 3.Now whenever you add new models to your world you can look (In the LightMap Density ViewPort) how to tweak the LightMap reselution to get near or into the Green Zone again. But Of course you can make exceptions depending of the effect you like to archive. Also remember that the higher the LightMap Res. the bigger the LightMaps.
