1. A concise explanation of the problem you’re experiencing.
I’m just wondering if anyone has any cool ideas about how you could represent a light source in scene. I’m not concerned with this light source illuminating other objects at all- what I would really want to do is turn this light off and on using a callback or sample property. I think a cool use case might be a landing strip for a runway. Would the particle rendering be able to achieve this?
I think a polygon or a sphere entity whose material changes like that would work here. There’s an example of creating entities with a dynamic material like that in this PR:

What kind of project are you working on?
hm thats a good idea, i’ll give it a go!
im basically trying to visualize train data. so when a train passes a switch on the track, i want to be able to indicate visually that the switch registered the train’s passing, which is an attribute of the underlying dataset.
That sounds like a cool app - will it be publicly accessible?
In any case, I’d love to see any screenshots/vids as you make more progress here.
