The first render of my scene is too slow. Any solution?

Hi I built a three js webpage https://about-thennarasu.netlify.app . I set a loading screen to show when the 3D models are being loaded. But even after the models are loaded, they take some time to render. Is there any way I can show a loading screen till all my loaded models are rendered. I couldn’t find a proper solution for this. Please help me if you have found any.
Thanks.

I’m not sure whether it will work, but at least it is easy to try.
