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 can i hide an actor from a scenecapture2d?


the title sums up my problem pretty good. i got a minimap set up using this tutorial: https://wiki.unrealengine.com/UMG_Mini-Map

problem is that i'm working on a vr game and so i have to put the minimap as a 3d widget in the world. thats ok, but i don't want the minimap widget to be shown ON the minimap itself. looks a bit like minimap-ception. i put in a picture that maybe explains better. in the lower minimap you can see the widget. thats the thing i don't want.

how could i hide it from the scenecapture camera? do you know another way to implement a minimap, so i could go around this problem?

There's an attribute that might help you.

You can tell objects to be only visible to you or specifically not to you.

It's called "Owner no see" and "Only Owner See"

Hope this helps you out!

hy! thanks for your answer. i tried it, but the problem is the "Set Only Owner See" node only accepts primitive components and no child actors or actors. also i can't cast an actor to a primitive component.

do i use it wrong? or is it simply not the way to with my problem?

You can just set it in the actor itself.

Also to modify the actor within that child actor you'd need to cast to the class it contains.

alt text Baseservice is the class I assigned the child actor.

alright i found the only onwer see attribute. if i click it i couldn't see the minimap anymore. what i did to resolve this is in the picture.

i don't understand what you mean with "cast it to the class it contains". the MiniActor contains a Widget so i cast it to a widget? do i have to do this?

because it seems like it works as intended.
