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"

Changing texture offset based on light direction

So pretty much I'm trying to make an eye material based on the ones in Sonic Lost World. I have a specular emissive texture masked by the iris, and a shine set to always be opposite of the specular's position. alt text

The issue I'm having with this is, I need to know how I can change the specular texture (light green)'s offset depending on the light direction relative to the character. Additionally I'd need to clamp the offset between some set values. I have no idea where to start with this and to boot I'm still learning my way around Unreal.
