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 use screen position output in a material with user interface domain?

Hey! I wanted to create a wavy distortion effect on a UI material, and figured screen position output would work like WPO in surface materials, but I can't figure out what kind of input it wants. I tried panning noise, sining time and inputing static numbers but they all just make it invisible.

How can I achieve similar effects to panning noise on WPO on surface materials for UI materials, for example to make spooky text or wavy images?

Is this in a widget or for 3D text? If it is for an object in a level, the screen position offset should function as you mentioned with something like a noise, but make sure the object is properly tessellated as it may just be moving the whole thing off screen in one big chunk.

It is for a widget. More specifically a font material. I want to make letters that dance around a bit.

Perfect! Thanks! When I think world position I didn't think screen position, but of course they are linked... Node graph for dancing text in world space (text render component) Node graph for dancing text for umg Dancing text in umg widget dancing text in world space text render component

Thanks damn-life for the answer. I'm trying to get the font distort like that. Would a similar approach produce similar effect to this? I'm trying to figure out how to do it but I'm running through some issues
