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"

Keep slider position after reactivating the widget

Hello UE4 developers! I'm solving material change system for my work project. The goal is to click on asset and change color via HSV sliders. Everything works fine except one thing. Whenever i click again on the same asset where the color has been changed my material is reseted back to original one and 0,0,0 values on sliders. Any tips how to keep sliders on their postions after setting them? Thanks in advance to everyone for tips :)

PS: Wud love to know at least how to add number values to those sliders.

Problem is super "simple" you add a new widget class everytime when you click on the door.. After you add this widget, your blueprint setting parameter on material via the added widget.. That means actually you set default "Color Pick" from newly added widget in tick..

I think you should save Color in BP_Door itself and update them from Widget or you can save a created widget object reference in your BP_Door and check if you have valid widget you should set visibility instead of creating a new widget..

you are welcome.. but this code will not work if you wanna more door :) because you will do for loop on all added material widget and set color with each iteration.. Try this instead of foor loop (sry i dont have ue4 on my fulltime work pc) alt text
