Here is what I found for you 🧠 #1212749866598400060 message

Based on the information found in the Needle Engine documentation and types, regarding your requirement to light plane meshes such as floors or tables with point lights in real-time mode, you should consider using the Light component. Here's a summary of how the Light component works, which supports different types of lights including point lights.

export declare class Light extends Behaviour {
    private type; // This allows specifying the type of light.
    range: number; // Applicable to point lights, specifying the range of the light.
    color: Color; // The color of the light.
    intensity: number; // The brightness of the light.
    ...
    createLight(): void; // Method to create and configure the light.
    ...
}

A few tips for using point lights to illuminate your meshes in real-time:

Ensure the type of the Light is set to LightType.Point to create a point light.
Adjust the range to control how far the light reaches.
Set the color and intensity to get the desired lighting effect.
Properly position your light in the scene so it illuminates your target meshes effectively.

Remember, lighting effectiveness in real-time also depends on other factors such as the material properties of the meshes. Make sure they are set to interact appropriately with the lighting in your scene.

I need it to work in QuickLook / AR mode

#

there is spot light above this light which cast shadow on plane under, with shadowcatcher. But I need to catch the light. I can fake it with plane gradieeent transparency and alfa, butwould be great to have it realtime

ok https://engine.needle.tools/samples/shadow-catcher/?overlay=samples&room=needle519 this solved my problem

Shadow Catcher

Render additive or masked transparent shadows, great for AR

Glad to hear! Yes, that sample shows how to use both light and shadow catchers 🙂

Yep but its not working on IOS AR mode, or is it? I saw just white plane.

Hey 👋 while QuickLook currently doesn't support custom shaders, there should at least be shadows affecting the environment out-of-the-box. Apple doesn't support custom lights in QuickLook right now, once they do, we will add that functionality.

Depending on your scene you could also use a trick and bake lighting to a emissive texture for the floor.
