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"

Reverse doesn't work for both parameters, what am I doing wrong?

I have this blueprint that mostly works...but the reverse doesn't update the second parameter.

Hi!

Maybe your problem not in blueprint. I created blueprint with a box mesh. I created material with two parameters. And created graph similar your.

Yeah did you try outputting the two timeline values to a printstring? just to confirm that the value changes when reversing? Are you SURE you have your Scalar parameter value hooked up in your material? (screenshot of the material graph would be helpful). A timeline simply not updating one of it's parameters would be a very serious bug :)

thanks

It plays fine forward, it just doesn't play backwards. The material is fine and I can see the time moving forward and back on the timeline. It just isn't updating the second parameter correctly in reverse. It gets stuck. Then, I can hit play again and it doesn't always start out correctly.
