Render light problem

[ZioLollo]

I would like to make a rendering of the fairground pavilion I made, the measures are 50 meters x 50 meters, it is a very large area. If I use the sunlight the shadows are too sharp, if I use the ceiling light I have to put so many that the rendering is too slow to make. Is there a way to have a diffused and uniform brightness?


I did a thousand tests, but I could not get a good result, I need some advice

You will have to add some lights. This tip might help you.
