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"

Particle Lights won't appear in-game.

Hey guys,

My first time posting here, so apologies if it is in the wrong section. I'm just running into an issue with have lights attached to my particle effects in a Paper2D scene. I have a pretty basic setup of just some floating lights attached to a cascade particle, that are supposed to light up the background and flipbook sprites surrounding them.

When I have it in the preview mode the lights work perfectly: alt text

As you can see here.

Whereas if I have it in play mode on the exact same spot, only the stationary point lights show up correctly and not the particle lights (which still appear as particles but not the lights): alt text

I'm assuming that this is not a particle error, but an error with possibly the camera or the sprite materials. Here is also a screenshot of the light setup in cascade: alt text

As extra info:

  • The sprites surrounding it are a tileset and regular sprites & flipbooks.

  • They are all the MaskedLitSpriteMaterial, with some background sprites that are TranslucentLitSpriteMaterial.

  • There isn't any directional light in the scene.

Hopefully you can help me! Thanks!

So I found out that for some reason or other, the lights will only appear when they are set to high quality lights in cascade. So this may be an extremely specific circumstance, but if this happens to anyone else, that is how I solved it. Translucent objects behind the particle can also have odd effects too.
