Strange behavior of Front Viewport?

[sdombrowski4163]

I've had this happen twice, but have been unable to figure out the steps needed to reproduce the error consistently.

What happens is that I'm in a maximized Perspective view and when I hit "F" to switch to a Front view, instead I get some sort of quasi-orthographic view that's almost like the front/bottom/left orthagonal view if you click that particular corner of the ViewCube, but slightly rotated towards the Front View. (see screen shot) Toggling between any other view and the Front view, either via keyboard shortcut, or the pull-down viewport menu, does not clear the error... it goes back to the strange rotated orthagonal view. Clicking on Front in the ViewCube results in normal expected behavior. Un-maximizing that view (which happens to be the bottom right viewport), activating a different viewport, then switching to a Front view results in the normal expected behavior.

Resetting and starting with a fresh scene restores normal behavior to all four viewports. If I re-open the .max file that exhibited the strange Front view behavior, the problem returns. If I merge that file's geometry into a new file, the problem goes away, so it seems to not be geometry related. I have not experienced this on Max Design 2013 or earlier, just 2014.

I'll submit a bug report in a moment, but I wanted to see if anyone else has had this happen, or if perhaps I'd turned on a new "feature" by accident.

I've seen this or something similar, but not sure which file did this and cannot reproduce it on the fly.

the same problem here!

Works fine here, but I do tend to kill the viewcube immediately after running Max for the 1st time. I wonder if it is viewcube related?

I also recall (vaguely) there being a problem with switching a viewport from a camera view where the camera had a Camera Correction modifier on it, but was a while ago not in 2014. The viewport "retained" the camera correction when it obviously shouldn't have done (IIRC).

[sdombrowski4163]

I've experience the camera correction problem you mentioned before, but I haven't tried to replicate it in 2014 yet. In once scene where my recent problem happened, I do have a camera, but it hasn't had a camera correction modifier applied to it. In the other scene, no camera whatsoever. *shrug*

I'll investigate the viewcube tomorrow when I have some time to throw at it. Thanks for the tip.

/stdplugs/AutoCamMax.gup (rename so it can't be loaded). Do so at your own risk, ofc.

AFAIK the strange perspective view bug after a camera correction modifier got removed or you switched the view was explicitely fixed for Max 2014

[YVESMOREAU2311]

Same here, when pressing 'L', instead of having the normal left view, i had the left view, but the X axis was rotated something like 45 degres...
when pressing the "left" side of the small viewcube, it was ok

could only reproduce it on one scene

spacefrog: It is definitely not fixed. I have encountered the problem many times in Max 2014. I have P key mapped to script where it sets view to perspective and FoV to 90°, because Max always resets FoV for perspective views ever since 2010 version. So thats how i work around it.

But thanks to the bug, i had to add one more line to the script to first switch to top view, and then to perspective view, to reset view and get rid of skewed view after switching from camera corrected camera. It works, but now i always end up looking from the top. I got used to it, but i was hoping in Max 2014, the bug is resolved. So i removed the top view line from my script, but it took me just an hour to encounter skewed perspective view bug in 2014. So it is definitely not fixed.

same bug today with max 2014 sp1...

Same problem here. Happens rarely, but it does happen. Glad someone posted this so I didn't have to. 🙂

Not glad there is no solution yet. 😞

Ok, this IS weird. I’m using 3ds Max 2014 x64 SP1. I tried replicating the behavior described in the original post. Created a simple cube, maximized perspective viewport, and pressed F for Front viewport. Worked fine.

Then I went back to perspective view (using the Home button on the viewcube or just switching back to quad switching), then pressed L for left viewport. My cube was rotated (see attached figure). I reset the cube to perspective view.

If I go directly to left viewport from Perspective, then go back and forth from perspective view to Left viewport, (L key), everything works fine. If I then, from perspective view, press F, go back to perspective and then press L, the cube is rotated. So my left viewport malfunctions only after switching to the Front viewport.

So, my experiment, (with an N of one), is that the Front viewport is messing things up, as the original poster postulated. My front viewport works as intended, but after switching to front, the left viewport does not function as intended. And, all of this has to be started from the lower right viewport (the original perspective view). If I start in one of the other viewports and toggle between views, the behavior does not occur.

In addition, so far this is not a rare occurrence. It is happening every time I switch viewports in the following sequence as shown in my attached image: from perspective (figure 1), to front (figure 2) to perspective (figure 3) to left (figure 4.)

I wish I cold replicate your problem. I followed your workflow and couldn't get it to work.

Same thing happened to me today.
I was modeling an object, and when I went from front view to left (by pressing L) the object looked rotated.
If I switch to a different view everything is OK. It doesn't matter from which view I go to the left one, the problem is there.

Curiouser and curiouser. This glitch happens to some, but in different ways, and it doesn't happen at all to others. I guess some of us got special versions of SP1 where our 3ds Max program has become self-aware and is now making decisions on its own.

Report this bug, or wait to see how advanced the AI will become? Will we be assimilated?

[insleight]

I fixed it in my scene. 

Try going to Views>Viewport configuration>Layount and choose a different layout.  That fixed it for me. 

I encountered the problem on a new scene, after creating a plane and duplicating it a few times. 

[jneilon]

We have the same issue. SP1 is also installed. 

[rkigarashi]

I also had the same problem in 3ds Max 2014. SP1 is not installed for me, so it's not that.

This happened twice: once when using a Radeon 7770 and once on a Geforce GTX 650.

Both times it happened when switching from a VRay camera view (safe frames on) to front view (by pressing F).

The problem goes away when loading another file and then loading the first file again. Or as stated above when creating a new viewport layout.

Attached is a simple .max file where the viewport is stuck in the odd skewed view. You can see that the objects are all skewed. And if you rotate the viewport horizontally 180 degrees in either direction, there is a strange snapping of the viewport and the objects are skewed in a different direction.

Note: The attached file was rotated away from "front" before saving, so you can just push F to clear the bug on that file. But when the bug normally appears, you obviously can't just hit F to clear the bug. I don't have any other save file with the bug.

I've never liked ViewCube but it's another solution !

[grue1970]

i had that, fixed it with the view cube.  when i hit the "u" key for "user view" it goes to top view haha.
