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"

Render Material to texture(Need Texture Buffer?)

Assume we have a material using an algorythm to create an image.

This created image / texture needs to be stored at runtime somewhere. In the next rendering step, the material reads the previously stored old texture of himself, adds the old results to the algorythm and creates a new image with them.

How can that be implemented in UE4? In need some way to store the render result of the material at runtime.
