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"

Spotlight bug - like it's cut in half

For certain rotation, the light is cut / cropped. It happens to me in every scene in my project. What's going on? The ground is a Landscape. Unreal 4.4.0

Hi Oskar,

Can you tell me if this is happening if you create this in a new project or just the one you are currently using? If it's happening in a new project you can you tell me the repro steps to make the issue appear?

Also, is this happening with a point light or only with the spot light? Is it also, only happening with the landscape or any object in this area of your map? Can you try this without the material that you've got on you landscape as well?

Thank you!

Thank you for the answer. It was a good idea to check itw with different materials. As it turns out, it only happens with my 3-layer terrain material. When I drop a simple material on the landscape, everything is OK, the bug doesn't happen.

Here's my material setup: http://oskarswierad.com/public/ue4/ue4-spotlight-bug-terrain-material.png

Hi Oskar,

After opening and taking a look you have a vector constant set up as your Normal Map. This is limiting the view. If you're not planning on using a Normal map for your materials at all then just unpin this or plug in the attached PNG blank normal to get a good result.

I hope this helps!

Thank you, it solved the problem :) So a single (0.5, 0.5, 1.0) color isn't an equivalent of a plain normal map, as I incorrectly thought.
