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"

How do I set post processes in BP on key input

I have a slow motion set up so when i press 'Q', everything becomes slow motion ... now to add extra depth to the game I want it to feel like the slow motion is actually adrenaline.. so in level blueprint I have found 2 nodes, 'break post process settings', and 'make post process settings'.... What I want to do is when i press 'Q', it activates the 'fringe intensity'..... from here I have no idea how to set it up

I'm also interested, i remember that it was not possible when UE4 came out, but Epic had a plan to expose post process parameters for editing in BP...

You should be able to grab your camera from your character and apply post processing settings there - a First Person Camera Component, at least, has all the settings a normal post processing volume has :)

This would be done inside your character blueprint, or in C++.

This appears that you are assigning the variable First Person Camera to itself which seems unnecessary. What you will need to do is to get the camera component of your camera then get the post process settings from it.

Realize that using the post process node in its current state is a pain as it is giant and will override everything.

ah right thanks RimmyD, i had a feeling it was wrong, seems i was way off haha :D so what i have set up now is the input 'Q' pressed, linked to a flip/flop node, which is linked to the camera component with the fringe setting turned on to full .. its not working so i have definitely missed something :)

Have you set Override Fringe Intensity to true as well?

avatar image mikeystar93 Feb 06 '15 at 04:21 PM

I cant see a set override option anywhere ?

avatar image Jargon Feb 06 '15 at 04:23 PM

Here, this is how mine is set up - I just verified that this works. In your case, you would have Override Fringe Intensity ticked instead, and your variable hooked up to Fringe Intensity :)

The empty array hooked to Blendables is required, or it won't compile. alt text

thanks alot man, this is really helpful, the only node i cant seem to make is the set process settings in the top right of your screen shot

avatar image Jargon Feb 06 '15 at 04:51 PM

Pull a pin off of First Person Camera Component and type in "Set Post" and you should see it :)

avatar image mikeystar93 Feb 06 '15 at 05:27 PM

I am seriously too new to UE4 haha....right, i have everything set up as you have it, but to the fringe .. except i cant get the first person component, i forgot to add that to the previous comment

avatar image Jargon Feb 06 '15 at 05:34 PM

Okay - What's the template that you're using? First person, or something else?

avatar image mikeystar93 Feb 06 '15 at 05:37 PM

yeah its first person

avatar image Jargon Feb 06 '15 at 05:42 PM

Okay. I've added the camera compent via C++, as I recall. Can you try adding one in your character blueprint via the components menu?

avatar image mikeystar93 Feb 06 '15 at 05:55 PM

i tried that and its not working, its definitely me doing something wrong, most of the time if i mess something up its only a little but it seems to be alot with this one haha :D ill send a screenshot of what i have but if we cant resolve it then its fine, but thankyou very much for your time and patience with me :)

Does anyone know why you can´t do what Jargon did with an event tick?
