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"

Why does unreal need to compile shaders?

I'm just curious. some times, even when just having a material with a vec3 for color and nothing else, it needs to compile tens of shaders. and seeing how other engines pull this of without any compilation time, or at least a noticeable one, i was wondering what unreal's doing and why? is it just to achieve better quality at better performance and better support for all shadermodels or just how unreal works? thanks for your time :D

When you compile a material, Unreal will create optimized low-level shaders for every usage and combination of your material, like one for static usage, dynamic lighting, instanced meshes, etc. These shaders will then be used for PIE and packaging, not directly your graph.
