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"

Light baking incorrectly

I'm using UE for archviz and attempting to recreate tube lights - I'm doing this with a blueprint containing a light and a cylinder with an emissive material. The Light is scaled to the correct dimensions (90cm x 1cm) and is vertically orientated. After baking the light however it appears to have changed orientation - the baked light is horizontal. Is this a bug or am I doing something incorrectly?

...maybe it's a bug... I've seen the same post in the last few days by someone else too!

Ah - that's interesting, do you remember if the other post had an official response?

Same problem here!

Just had a sec to test - it's easily reproducible in a blank project, so must be a bug.alt text

I also noticed that moving from 4.18 to 4.19, all placed BP actors that had a pointlight with length have been rotated 90 degrees. I've also noticed it on certain spotlights being rotated as well. I'm sure it must be related.

Just wanted to bump this thread in hopes it gets fixed in an hotfix soon.
