How big is the draw dome?

Torkuda

I've seen it said that the way to get a ground prop that reaches the horizon is to make it bigger than the draw dome- how big is that?

That does not sound like advice for an Iray ground prop. The Dome is not real, i.e. it's infinite. Certainly one can make the ground prop large and angle the view to have it appearing to meet the horizon.

In Environment Options, if you set the Dome Mode to "Finite Sphere", the default dome size is 100 meters in radius from world center (200 meters in diameter).

Dome Radius: 100 (default) - this is in centimeters!
Dome Scale Multiplier: 100 (default) - like the label says, a multiplier for the Dome Radius
100 cm x 100 -> 10,000 cm (or 100 m)
