Appreciation for ClockworkOcean’s Contribution to Spline and Point Lights

I would like to express my sincere gratitude to ClockworkOcean for their invaluable assistance with Spline and Point Lights. Their guidance has helped me understand how to utilize these features effectively. Once again, thank you.

I have been attempting to comprehend and implement the blueprint, but regrettably, I have been unable to find a solution for creating animations. If anyone is able to offer assistance, I would be extremely grateful for your support.

Spline and Point Lights

Hi I’m currently trying and failing to write a blueprint to place many pointlights along a spline to basically curve them. Does anyone know how I could do it? I’ve seen many use splines to arrange static meshes along curves, but cant find anything about lights.

I have added two nodes, “Set Intensity” and “Set Light Color,” after the “Add Rect Light Component” node. I have ensured that they are exposed to Cinematics.

While working with the Sequencer, I can access the “Intensity” and “Light color” parameters, but unfortunately, they do not function as an animation. I would greatly appreciate guidance on how to incorporate variable values into the Level Sequencer to create animations for intensity and colors.

Thank you in advance for your assistance.

Please refer to the accompanying screenshots.

I don’t really use the sequencer, as it’s not easy for this sort of thing.

I think you have to put the lights in your level and reference them

There’s only 2 variables exposed, in your code, but N lights. How can it work?

Maybe if you describe what you’re trying to do with the lights, I can help…?

@ClockworkOcean

be if you describe what you’re trying to

I tried to think of the easiest way to explain it.
N is the number of lights along the spline.
If I say that each light on the spline is about 100 centimeters long, then a 10-meter spline will have 10 lights.

1. select Add Rect Light Component to adjust the brightness color of the light in the Detail window.
   However, when you go to the Sequencer for animation, you cannot load a variable value to adjust the brightness and color of the light. As a result, I will not be able to create animations that change the color of the lights.

2. To adjust the brightness and color of the light
   I created a Set intensity, set Light Color node and imported it into Sequencer to create a keyframe, but there is no effect.

3. By bringing up each light in to sequencer, I can create keyframes to change the brightness and color of the light.
   That’s probably the best way to go.
   The reason we want to use the function N with Spline is because it’s not always easy to set up multiple lights at regular intervals.

Thank you so much for taking the time to reply, I think you must be busy.
I hope you have a great week.

To be clear, you can put them automatically on a spline, but then controlling them from the blueprint is the answer, not a sequencer.

You’re right.
Thank you for your always helpful comments.
