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"

Same issue here. I tried the version 4.18.1 as well, but this time it takes forever to "compile shaders" and uses all my CPU.

Using: MacBook Pro (Retina, 15-inch, Mid 2015)), 2.8 GHz Intel Core i7 (4 cores), 16 GB 1600 MHz DDR3, AMD Radeon R9 M370X 2 GB, Intel Iris Pro 1536 MB.

Given the download size is so big, I am hesitating now to download any other version of Unreal Engine 4.

Same issue here. Since I upgraded to 4.18, I cannot open the Unreal Editor for 4.7, 4.8. 4.9. 4.10. However, I can open the Unreal editor for 4.16, 4.17, 4.18 I haven't tried the intermediate versions yet... but something has changed with 4.18

I've switched to Unity3D. I didn't want to, but I had no choice...
