   zbuffer issue dx 10
  I am having an issue with depth fighting between a planet and its rings in dx 10. Is there a way to change to wbuffering or flat distance value. I am using 32 bit float zbuffers and the resolution is clearly not sufficient for the task. I am also setting the near and far to the front and far edges of the planet and rings and to 1 if the near edge is less than 1. I clear the buffer before and after rendering to prevent issues with moons and stars. It works far away but I get z fighting when I get within 6x of the radius of the planet.
