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"

Wrong way implementation using material gradients for streets

I have a spline which is used for creating streets that share a single material for the ground. For performance matters, I want to achieve the cheapest solution for checking if a car is going wrong way or not. I thought about volumes to check the direction, but later I thought about using the own ground material with a special gradient that specifies flow direction. Is there any way to retrieve the color at any point on the street using line tracing or something like that? I would be using red for the right side of the road, blue for intersections and green for the left side. About the UV, I know it's going to create gaps because of the gradient being repeated along the axis, but I think this can be easily treated on code.

So, is there any way to create that separate material layer and raycasting/line tracing to get it's color on any given point?
