= SUMMARY =

This article provides a few tips for using the SunRise and SunSet Shaders.


 * Make sure that your ground object is very large so that it reaches the horizon of your scene. As a reference, position a circle in the XZ plane and scale it to the far plane of your camera (default 32768). From here you can see if your ground plane object is large enough to reach the horizon. If not, gaps appear that get worse as you raise the camera. Also, set Altitude to -0.6; this helps remove black horizons.
 * It makes no difference if you move the sphere for the atmosphere shader on the y-axis. You can use Rendermap to convert it to a bitmap, apply it as a normal 2D texture, and either drop the sphere down, or use Paint to remove any offending areas. If the shader has animated parameters, this solution does not work.
