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"

Hello,

I thought that you may want to knwo that there is a known limitation with doing fading with blueprints and paper2d:

https://answers.unrealengine.com/questions/88145/why-matinee-fade-track-does-not-work-on-a-paper2d.html

"The fade track feature is applied in our postprocessing which is not used in that case. Getting that feature would require a full screen pass (or we can fold it into another pass) or all materials would need to make a color transformation. We don't have that yet - fixing that should be part of the TTP. "

We are currently working on fixing this issue.

First your material needs to be translucent. You set the opacity value(or its multiplier value) as a parameter. Then create a dynamic material instance in the blueprint > get that parameter > change it via Timeline whenever you please.

I also suggest having two instances of your mesh - one with a nontranslucent material so that you can have opaque elements and a hidden "fade" mesh that you switch to when you want to fade the BP out.
