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"

Need to find equivalent code for Deferred Rendering as I have found for Forward Rendering

Hey all, need some of your grand knowledge to be bestowed upon me for this next question. I am currently working with some interesting stuff that Tom Looman found/used in his Disney Facilier effect forum post, which you can see here:


What i need to find, however, is the equivalent of some code that he used, but able to be used in deferred rendering.

The code he used is " return Square(Texture2DSampleLevel(LightAttenuationTexture, LightAttenuationTextureSampler, UV, 0)); " which is found in the engine’s shader folder at …/4.14/Engine/Shaders/Common.usf and contains the function GetPerPixelLightAttenuation(float2 UV);

The problem with that, however, is that the code only works with forward rendering enabled. I don't really understand or know the difference between forward and deferred rendering, but I have heard that deferred is more versatile/better/less limited and I would really like to not cripple my project right from the get go. So if anyone knows how to get the equivalent of that code to work with deferred rendering, I would be very appreciative.

For reference, when plugging the output of that code (when used in a custom node) into the emissive of a material, the output is the image below: alt text

There is no equivalent code, since deferred works differently.
