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"

How to fade on a light?

Hi! I need to fade on a movable light.

To do that I've unchecked the visibility property for the point light and lowered it's brightness to 0. Then I've tried to turn it visible and loop from 0 to a brightness value using a custom delayed for macro (default for won't do the trick here, source), yet the light does not turn on.

Another approach I've made has been to make the point light visible and call the function I use to increase the brightness from a SetTimerByFunctionName node, but it yields the same result, light does not turn on.

Any clues on how to pull this off?

Thanks!

Timelines are meant to be used for this exact type of operation.

Can even use a new ease in-out curve :)

For some reason I thought of timelines as only appliable to particles... Thanks!

not at all, a timeline is just interpolating data. Can be used for whatever you want.
