weird snapping occurring (WHEN NO SNAPS ARE ENABLED)
show user profile  jpedleham
Hi, im working in a rather large model (distance wise, not particularly poly heavy) and when i try to either drag out a primitive or move an object, unless i use the spinners, the gizmo just snaps as if to a grid but i have all of the snaps turned off. its really frustrating. i know max does this sometimes if the model is big but its jumping in large increments. if i zoom in its less intense but its still snapping to invisible gridlines.
Can anyone help?

Max is poor at dealing with huge distances if your scene scale is inappropriate. If your units we are millimetres for example and you start modelling things a few hundred metres away from the origin, it will flip out as it cannot maintain that accuracy.

It's stated in the docs:

"Because of the nature of digital floating-point calculations, distances that are extremely large or extremely small can cause round-off error. Symptoms of round-off error include trouble navigating (zooming and panning become too fast or too slow), unwanted viewport clipping, and unexpected flipping of normals."

Sounds like this could be the issue in your case too. So, try the following:

Make sure your scene is roughly centered around the origin (0,0,0).
Round-off error increases at large distances from the origin.

Make sure no significant detail in the scene is smaller than one generic 3ds Max unit.
Note: The Rescale World Units utility alters the scale of world units throughout the entire scene, or selected objects.

check its not set to 2.5 snaps if your in perspective view

it sounds more like what luxxeon said though

Yeah it was the units issue. i didnt realise that i needed to merge it into a new scene with the correct units to fix it though :)
Cheers guys, it was doing my head in!
