Can't clone or instantiate GSplatComponent

Help & Support

Project link: PlayCanvas 3D HTML5 Game Engine

As shown in the project, when I try to clone or instantiate a template with a GSplat it fails with the following exception:

Note: It works fine with the Render Component.

TypeError: Cannot read properties of null (reading 'clone')

The function

cloneComponent(entity, clone) {

        const gSplatComponent = entity.gsplat;

        // copy properties
        const data = {};
        for (let i = 0; i < _properties.length; i++) {
            data[_properties[i]] = gSplatComponent[_properties[i]];
        }
        data.enabled = gSplatComponent.enabled;

        // gsplat instance cannot be used this way, remove it and manually clone it later
        delete data.instance;

        // clone component
        const component = this.addComponent(clone, data);

        // clone gsplat instance
        component.instance = gSplatComponent.instance.clone();

        if (gSplatComponent.customAabb) {
            component.customAabb = gSplatComponent.customAabb.clone();
        }

        return component;
    }

at line component.instance = gSplatComponent.instance.clone(); the property gSplatComponent.instance is null.

This looks like a bug. Is this behavior expected?

Thanks.

It’s likely not expected. Please create an issue here:

This example clones splat and that works thought: PlayCanvas Examples
