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"

Some advance questions about pointlight

I am working on a dynamically generated star simulator. I am currently using a single point-light as the center of a star.

So made the attenuation radius of the star really high 5000000 then I noticed at a point around 130000 away from the star, the light of the star completely vanishes. I decided to increase the attenuation radius of the light to 15000000 then the light covered the rest of the parts but it still faded away this time around 140000 and I increased the radius of the light further to 150000000 and it lit up a long range but still vanished at a point not that far away.

I am using a movable light and not using square and I had to increase the light fall off exponent to 6000 to get the effect so that the light is fading towards the end of the borders(at 5000000 radius). However if I increase the radius, I need to increase the falloff to get a good effect.
