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"

Problems with dynamic shadow

I'm having some problems with lighting in Unreal Engine 4.4.3. As shown in the video below, the light is bleeding through the door if I am too far away from it (this also happens in game, not just in the editor).

It is a stationary spot light. Light maps are baked using Production Level quality. The door mesh is a dynamic (movable) mesh since the player is able to open the door, so it casts a dynamic shadow, which I think is the problem here?

I don't know how to fix this... I also increased the light map resolution of the ground mesh quite a bit to see whether the resolution was the problem but this seems not to be the case.

Hi Dalon,

The best option here would be to use either a Static Spotlight or to use a Movable light. These will give you the most control and the best results.

With the stationary light you are seeing the stationary light switching between the static and the dynamic lighting. The Stationary Spot Light, unlike other movable lights, does not have the option to adjust the cascaded shadow distance. By using a movable light you will no see this popping and the light can be disabled if the lighting doesn't need to be baked into a lightmap.

I hope this helps! :)
