Only preload assets which are part of exported scene

Help & Support

From memory something like, for example, the scene data will contain a render components reference to a material, but not the material’s reference to a texture. This can be found from processing the material asset in the asset registry.

Ok I got it working now! Thank you very much for the help!
I did implement the loading of material/model/render a bit different tho.

When loading the scene data I check the type of the item and if it is a material, model or render component. I call the processItem function again, with the data of it. This way I only need to iterate the scene registry.

LoadScene.prototype.processItem = function (item) {
    let type = (typeof item);
    if (type === 'object') {
        if (Array.isArray(item)) {
            this.processArray(item);
        }
        else {
            this.processObject(item);
        }
    }
    else if (type === 'number') {
        // Check if the number matches an asset ID in the asset registry.
        let asset = this.app.assets.get(item);
        if (asset) {
            if (!this.requiredAssets.includes(item)) {
                this.requiredAssets.push(item);
                if (asset.type === "material" || asset.type === "model" || asset.type === "render" || asset.type === "template") {
                    this.processItem(asset.data);
                }
            }
        }
    }
};

Also asset.type === "template" should be processed as well or else if you have a script referencing a template which is not part of the scene. It wont load the meshinstances.

I’ve added it in my script above
