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"

why is Post process volume not appearing through camera

I cant seem to get bloom to work when playing. Here is what i did. I made a new project with the third person template. I added bloom to the level and hit play. I can see the bloom so everything is fine at this point. I went into Content>ThirdPersonBP>Blueprints and copied and pasted the ThirdPersonCharacter and renamed it myCharacter. I deleted the ThirdPersonCharacter from the scene. I went to setting>project setting>maps&modes and changed the default pawn class to myCharacter. The bloom is still in the scene at this point. After i hit play, i dont see any bloom. some of the other effects work during play but not bloom. Could someone help me with getting bloom to show during play?

There are 2 main ways to add post process effect to the world:

  • Add post process to the camera

  • Add post process by the Post Process Volume

In camera case you have to make sure you're using the same camera in game. Camera could be changed by various reasons, main is - player spawned new instance. To avoid this case just modify the camera settings inside the blueprint. Then even spawned camera will have same post effects.

Second is bound to volume camera currently located in. You could add PP volume in the world and check option - unbound, to make it infinitely large, so camera always will be within it.

PPV has priority setting if you're using several overlapping ones. Cameras have Post Process Blend Weight, where 0 is PPV 100%, and 1 is 100% camera PP.

Make sure your camera have no enabled Bloom setting set to 0. That will override the setting within PPV (same for PPV override if there are many PPVs).

you can also disable the camera post process by setting the blend weight.

I think the Post Process Volume (PPV) on your character's camera is overiding the other PPVs... I'd check this first :)

Ive messed with the ppv in my myCharacter camera but only some effects show through the camera. Is that the overiding part or is there some other way i can override?

I think the PPV material (Rendering Features > PPV Materials Array) on the active camera (whichever one is active at the moment) overrides everything else...
