Choppy moves in large scenes

Hi. Please help. I have large terrain. And all objects move jerky. If I move using controls bellow view port it moves smoothly but using mouse and gizmo it moves by increment of 50, berry choppy. How do i just movement level. Kind of like Wheel Zoom Increment in preferences but I need for movement


thank you

What version of 3ds Max are you using? Also, make sure you've got all the updates installed

Greg,

Is your terrain in a real world coordinate system ( ie some UTM or State Plane projection) that is far away from the origin [ 0,0,0 ] in 3ds Max ? If so, this is your issue. 3ds Max is not double-precision and does not function well with very large ( or very small ) coordinate systems.

If you can, it might make working with your scenes much easier if you can figure out a good offset to use ( and make sure to document it in-case you need to reference in further geometry or geo-located objects to the same offset ), but use that offset to move your terrain much closer to the origin.
