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"

Texture Samples inside Material Function not updating from Input Texture

Im creating a material function to hold the different effects I want to apply to a few materials. The function itself is working fine. However, if I have a Texture Sample that has a texture in it's parameters and I pipe in an Input Texture so I can update it from outside of my function, the new texture that I apply doesn't pass through. It keeps the value in its parameter.

I expected that functionality to work as a default, so if there wasn't a texture being provided it would just use the value it had, but instead it simply does not to pay attention my input.

Could you show me/us a screenshot?

Chance is that you needed to set the "use preview value as default" Also be sure its set up like this: alt text Like this, it should default to the chosen texture is no textureobject is added outside the function.
