Auto-perspective changing to perspective while orbiting - bug is back
Closed, InvalidPublic


System Information
manjaro linux - ati mobility radeon 4650

Blender Version
Broken: blender-2.70-8f1a6e2-linux-glibc211-x86_64.tar.bz2

Short description of error
The Auto-Perspective feature does what it's suppose to do, automatically changing the view to perspective while navigating away from direct views (front, top, side, etc). However, it always forces perspective mode while orbiting from any other user-defined view. This means it's impossible to orbit the view in orthographic mode. This should not happen as orthographic orbiting can be very beneficial to certain workflows.

I notice that this has been reported for previous versions of blender:

I am reporting it because this bug is back in it's full annoying glory in the 2.7 rc and also the latest build from buildbot.

Exact steps for others to reproduce the error
1.hit 5 to switch to ortho view mode.
2.Orbit and hit ALT to snap to front or side view

  1. Orbit away from side view

Blender will then throw you back in perspective mode.

Some times it doesnt do it. So repeat the steps again if it doesnt happen the first time. Try orbiting away from front view by mid click dragging up and down as well as left/right

I couldn't get this to happen, after trying many times.

between steps 2 and 3 are you releasing the mouse button and orbiting again?

I have uploaded a video demonstrating the bug with the latest build.

please pay attention to the unwanted viewing mode switch - ortho to perspective (0:17). It does it 99% of the time for me.

As far as I can tell this is working correctly.

Auto-perspective will _always_ move into perspective mode when moving out of an axis view, and you didnt address my question.

between steps 2 and 3 are you releasing the mouse button and orbiting again?

From your comments here, it seems like you just don't want auto-perspective (or want it to remember the perspective when last in user view).

this can be changed, but currently its working as intended.

I am sorry. Didnt realize it was a feature and the sudden new behavior seemed like a bug to me.
Yes, I would always expect blender to remember my viewing mode and only change it on request!

To answer your question: Yes, I am releasing the mid mouse button between steps 2 and 3.

Disabling auto perspective gives me back the previous and more predictable orbiting behavior.

So this is in fact not a bug. Sorry for wasting your time.
