Can you explain what you’re wanting to do exactly? Posting a gif that you said you didn’t make and saying you need help is not very descriptive.

If you’re asking for a finished script, you’re not going to get one here. That’s not how the forum works. You’re intended to attempt to solve your problem yourself, and come here for support if you have trouble.

This looks like they’re raycasting from the lamp part and drawing a cylinder or something with a SurfaceGui on it with LightInfluence = 1 on the ground where the raycast hits. The size of the cylinder is adjusted according to the angle the ray hits the ground at.

Note that this does not support non-flat terrain.

What I want to say is that I want to do that and I need the help and that GIF is a reference to what I need

Thank you for your response and sorry for posting this.
