Dear Dave LaRonde,
Really appreciating your efforts to replay to this thread. I thought 8 lights is nothing in a 3D scene, I have multiple light sources that illuminates different parts of a party stage. So i have to use add as many as lights of the same to get the good render. i didn’t faced any issues with rendering. 10 second scene is rendered in 15 minutes time that is much lesser when compared to other 3D platforms.
