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 to set to movable without loose lightmaps on actor?

Setting an actor to movable commonly loose its lightmaps, ok.

But, now we need lightmaps to be preserved because this time actors are white doors.

The whole building has lightmaps, doors too. Here comes the problem: Doors have open/close animations. When we set them to movable, lose lightmaps and visual difference between whole building and doors looks simply horrible.

Are there any solution to this scenario ? Thanks.

Hi Lord Pol,

You can enable the option for "Light as if Static" on the movable actor, but this setting is meant for Actors that will not change position too much. Something like a door would see really bad artifacts where it would likely turn black if it rotated too much and the shadow cast by the door on a statically lit floor would not change either.

Your options are to either use stationary lights that take into account movable actors and cast dynamic shadows for movable actors or if you need to keep the environment completely statically lit then you will want to adjust the Volume Lighting Samples placement to be more dense to help blend the actor better in the environment. This documentation should help explain this as well.
