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"

Fake-light on a dynamic amount of spots on a material

Hey there! I'm having a grid cell material which is applied to every cell on my grid, and I want to "light up" spots where the path on this grid traverses across. The result should look similar to this photoshopped sketch:

I know I could pass coordinates down via a material instance or parameter collection and generate a SphereMask inside the material, but obviously that only works if I know how many circles/points in the path I will have.

My thought was to place lights above each tile, and have the material somehow read the light information and multiply it with the whole opacity of the tile, so it would gradually fade out, but AFAIK there isn't a way to read lighting data from a material.

Does anyone have an idea on how to approach this? Many thanks!!
