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"

Accessing an integer within a material function


I've made a blueprint to change a materials color four times, according to the season of a level. This works, but I need to do it for a number of objects/blueprints. So I wanted to do it in an material function.

So I basically did the same thing that was working, only now I want to use the integer that defines which season it is from another blueprint that I have. The problem is that when I get the reference to the season control blueprint and plug it into my dynamic material function, it says it is accessing none.

I feel like I'm overlooking something obvious. Any help is appreciated. Also if there are easier ways to do some of the things I'm doing please let me know.

This is the system I'm using currently, which is working:

alt text

This is the material function that I made, that hopefully does the same thing: alt text

This is the way I'm controlling the seasons: alt text

And this is the way I would like to call the material function within a random blueprint: alt text

But as I said, getting the integer from the other blueprint seams to be a problem.

Thanks in advance!
