I'm having my first go at rendering a TG2 Planet from high orbit.
The trouble is if I look straight down (rotation -90,0,0) at the planet even the 3D render preview
takes forever, well I've left it for a few hours and its still there saying "Rendering... detail 5".
If I switch the water off or set the camera rotation to (-89, 0,0) the it renders at
a normal speed.
Have I hit a big ?
The lake is too big! It's 1e+008 meters in radius. Apparently if it is bigger than 1.167878e+007 meters in radius, terragen has a heart attack. The planet in your scene is only 6.378e+006 meters in radius. The lake is bigger than the planet.
