Hi Diana, If you are controlling the camera from a user defined path or simulation then you are best to not attach a camera manipulator to the viewer and just set the viewer's master camera directly yourself. If you do try to set the camera's view matrix yourself but still have a camera

Hi Lv, If you have a scene with a very large distance range then depth precision is an awkward issue to deal with - the lower the near/far ratio the lower the precision. To retain precision you have to either push out the near plane or pull in the far plane, and they work as ratios so doubling
