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"

Hi Kemal Thats just your sphere reflection capture acting normal, as you know real time reflection even with ssr are very expensive, ue does an optimization to help with this, that line what you see in your screenshot is just a sharp variation in your roughness, because your mesh is only affected by the radius of your reflection sphere you have one visual result, meanwhile the part that is not affected by the sphere has another roughness value.

To solve this issue, you have 2 options, put another reflection capture and UE will blend every boundary, or you can make that one bigger, you will lose you quality in the reflection directionality but also is not a good idea fill the whole thing with thousand of sphere reflection because this also affect performance.

Hope this helps Cheers
