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"

Messed-up lightmapping

Good day,

I'm currently experiencing some issues with a custom mesh i'm trying to import into my game. Since i'm a bloody beginner in 3D-modelling and the stuff that comes with it, lightmapping brings some issues. I went through the following steps:

Mesh with no UV-Map and therefore no lightmap:

both channels are empty:

As you can see there's literally no lightning at all after lightning-build.

I went on auto-creating a simple UV-Map in blender and left the lightmapping-job to unreal:

uv-map channel:

lightmap channel created by unreal:

Today i tried creating a lightmap as a second uv-map in blender with the following results:

uv-map (the same as before):

blender-created lightmap:

In comparison:

As you can see there are still plenty of rendering errors although the black parts vary from the blender-lightmap to the unreal-lightmap. Any help would be greatly appreciated! Thanks in advance.
