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"

Get Not Rendered Actors?


Here is the question. I am planning to have a forest where trees have a chance to become creepy if the player is not looking at them. It is unfortunately not a first person game but a third person. So what I need is a way that I can check, certain actors are not rendered in the viewport/game screen. For example, the tree is far away and behind the player.

Is there any way to do this via blueprint?

If the question is not simple to answer, I would like to go on with Mister Rama's "get rendered actors" blueprint library node.

It looks awesome but I have a problem with it :(

First of all let me show you my blueprint, simple at best.

This is a simple blueprint that searches for a Test Actor I have selected in my map. The moment I start the game, the test actor is not on the viewport screen, so, when I check if the array contains the item, I get "True", as it is "get NOT rendered" node. And when I get my camera towards the test actor, I get "Found". Everything is fine, until I get my screen away from the test actor, which is not rendered anymore. I still get "Found", no matter what I do.

I tried to clean the array too before the 2 seconds delay, for a fresh render checking, but it's no use.

Problem seems to be that, the render check is not reseting itself, and/or completely ignoring "Min Recent Time".

Another example would be this blueprint;

At this one, I search for the candle blueprint. And no matter what I do, the blueprint is always considered "NOT rendered". There is no tranculency on materials. Its just a low poly candle.

There is a high chance I am doing this all terribly wrong. Is there anyway anyone can help?

Thank you all for your time and reading!
