3D max dissapearing models problem

[biotech]

Does anyone know the cure for this?

You are working on a model, you have zoomed into it before to make tiny details, all was fine, much later on you try and zoom in again, but instead of being able to get to your details, the model starts to disappear as it approaches the screen.

Its probably something really simple, but its as annoying as hell at the moment.

It could be a scaling issue. If your object is too small, it will "intersect" with the camera at close distance and become invisible as you are passing through it. If scaling the object up doesn't fix it, I was wrong...

Theres no camera in the scene, and the model is dozens of meters in size.

The issue only happens in the perspective view, if I switch to user view, I can still zoom in, although the model has some strange perspective applied to it.

In perspective you have 2 zoom tools one affects basicly the lens (creates those distorted views the other is a plain zoom to fix or reset this right click the upper left corner of the viewport. Choose configure in the rendering method tab look to the lower right and FIELD OF VIEW it should be 40~60 if it is like 120 etc that is your problem.

Another fix could be for clipping this you need to select a poly or small object in scene and click the white box with arrows on the corners(brackets etc) Called zoom extends or press "z"

hope this helps

It was set at 45.

The zoom extent is helping a little, but its still happening, thanks anyway.

In my experience it's an issue with the scale of the scene.

Once I downloaded a whole set of models that for whatever reason were scaled in micro units. The average person was .1" tall.

If I scale them all up to the appropriate size (5'-6') I don't experience the issue.

So my simple solution is to model in a decent (sometimes exaggerated) scale then scale it down if you need to insert your model into a scaled scene.

What are you modeling, and what is the width & height?

Also, as I read back into your original post I see that is was fine at one time. Sometimes it seems like the perspective camera can adapt to the size of the scene, and just needs to be reset. Just hit Z every once and a while (which fits the camera to the selected extents) to reset the camera position and you should be fine.

It's your near-far clipping plane. You can adjust this by right-clicking on the "Perspective" tag in the upper left of the viewport, then click on "Viewport Clipping". that'll pop up a gizmo on the right side of the viewport. drag the two arrows to the top and bottom of that gizmo, and you should get some more of that model displayed.
Good luck.
