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"

Setting Near Clip plane to 0 messed up rendering.

I had an issue earlier this year where my project seemed corrupted and rendering was messed up really badly.

https://answers.unrealengine.com/questions/402430/objects-are-invisible-unless-selected-after-editor.html this issue specifically.

Yesterday I set the Near Clipping plane to 0 in Blender, and it sort of did the same thing. Turns out setting the Near Clipping plane to 0 causes all kinds of issues.

Product Version: UE 4.12

Hey Sneggledex,

Yes, Setting the near clip plane to 0 is not something that you should do. You always need to have a value for the near clip plane, otherwise, all things that get mapped to Z are set to 0, which causes the issue.

Barring the 90's feel of the web page, this is a good resource of information about the Z-Buffer and your Clipping Plane. https://www.sjbaker.org/steve/omniv/love_your_z_buffer.html
