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"

Hey Bagner,

Thank you for submitting this post. I have reproduced this issue and logged a report for it here: https://issues.unrealengine.com/issue/UE-43089

I will say though it appears that Dbuffer decals are just broken when used as a decal component in blueprint. It doesn't matter if a translucent material is present or not.

I'm sorry to say this but at this time you may need to use decal actors instead.

You can track the report's status as the issue is reviewed by our development staff. Please be aware that this issue may not be prioritized or fixed soon.
