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"

Hi!

The Sine node generates values from -1 to 1. You need add the offset.

Just some more specific info:

There is a ConstantBiasScale node almost specifically for this. To go from "-1 to 1" to "0 - 1" you need to add 1 (0 to 2) and divide by 2 ( 0 to 1). This node by default does this.
