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 to access a value from material in BP?

Is it possible to read a value at specified output from specified material in blueprints? For example, how to access this value in blueprint from specified material instance?

alt text

I can't see any 'output' options for materials that could be used for that. Does this mean that I need to recreate this calculation in blueprint? If yes, I see that we have Frac and Sin in blueprints, but what's the equivalent of material's Time node output?

I will be grateful for some tips!

I see that I probably won't be able to recreate the 'Time' node in blueprints to achieve the same value as in material instance... Well, I'll need to calculate all this a little differently in blueprints and pass to material parameter every tick...

Remember that tick is frame dependent, so you will want to use delta time for that. Every tick, add delta time to a float that is keeping track of your current total elapsed time, and use that for your sine.

I Wish there was output parameters (a method of storing material variables and access them in blueprint) in UE4's materials
