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"

HELP! UE4 4.18 won't render decals opaque

Someone please help me asap! I am in the middle of a project, nearly finished, and for some reason UE4 4.18.3 will not render decals opaque. Yes they work translucent but it looks rubbish. I am trying to do blood stains but i want them opaque like I used to be able to in previous versions.

I have all the settings setup in rendering such as Dbuffer and Zpass etc but none of it works. I keep getting this "SM5: Defered decal must use transparency, better for performance". I have tried literally everything and can't get 4.18 to use opaque decals.

I am not sure why you changed this but its the same in 4.19. The engine will not let me render nice looking opaque decals, no matter how many times i change the settings. I really hope someone can help me with this. When I change to opaque, the material disappears in the preview, this never happened before 4.18 that I recall. Thanks! Adam

You could just multiply the opacity in your material until it looks good (multiply by some amount and subtract a bit until you get a nice transition, saturate if you get visual errors without it), or change the opacity in your texture to something more harsh.

Thanks a lot man! I will give this a try tomorrow. I actually kinda got it to look better by using a scalar parameter and an add node so I can control the opacity in an instance. But with a multiply as well, that would probably work even better! Thanks very much for your time and help! :D

Best regards Adam
