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"

Shader compiler not discarding outdated shader jobs

When you change landscape material settings, UE begins immediately to compile shaders, adding compiler jobs for shading the terrain textures.

When you again change the material settings, updated, additional shader jobs are created, but the old shader are still active, visible in the compiling shader amount number.

Product Version: UE 4.10

Hi unit23 -

Currently this is expected behavior in the engine. Compiling a Material is the same as compiling C++ code for a project, it is an all or nothing activity for the CPU, unless you cancel it. I have added a feature request for you asking to allow the recompiling or saving of a material to function as a cancel if currently compiling as well, for reference UE-27574. I will keep you informed as our engineers evaluate the possibility of implementing this feature.

Thank You

Eric Ketchum
