Camera walk through jerky pan movement

[neculageorge]

Hi guys,

 

I am having an issue with the camera control in walk through mode.

 

When I try to move/strafe (W,S,A,D keys) it works smooth. But, when I pan with the mouse, I get a end to end movement instead of a smooth one. In other words, when I click drag and release the camera will not follow the trajectory of the mouse movement, instead it "jumps" from the position where I pressed the LMB to the position where I release it.

 

I know this is a small issue, but right now I am working on a project that needs quite accurate camera positioning and the matter became annoying.

 

Things that I've tried so far:

 

- adjusting the speed of the camera truck ("[" and "]" keys). this does not seem to work for panning unfortunately

- opening different files in which camera worked fine before, now it doesn't. So I figured this is not file related.

- reset the ini file (delete it). Still does not work.

 

Any ideas? Sorry if this thread has been discussed before, I did not find any other that would fix this.

 

Thank you

Try merging it all in to a new file perhaps?

Thanks for the reply Chris, let's see... I am doing it right now. Aaand nope... The problem persists. :| Even if I reset the scene and create a new camera, same thing.

 

I assume it's a file independent setting that I am missing (?)

Have you added the latest service packs and hotfixes for your version of max? it could be a bug in the latest version but as it normal when you open another scene file you say "it works as normal"

 

 

Have you changed the trajectory along the path to make it into a smooth flow?

 

 

when does this happen? just when you play the animation in the viewport or when your rendering out to watch it as an AVI and you can see it,

Not sure about this, but the difference when you are in walk trout mode the center of movement depends of the camera position(simulating a person walking)

when you do a pan or zoom in 3D max depends of the world center or the last object you selected. If you object, mesh in the scene is far away from the 0,0,0 coordinates the zoom or panning will behave strangely. One solution or try can be select an object right where you are or looking at press perspective view (P key) then adjust your zoom and try to pan. any extra jerkins will be problems of your video card managing your scene. You can try to turn off adaptive degradation too.

Thanks guys!

 

@ Tony: I do have the latest stuff. I believe that the issue is not file related. I tried every possible reset/open old file with cameras/make a new file combination that I could think of. The problem happens when I pan/tilt the camera in walk through mode while tilting in viewport. I do not have a path since I need static renders but with fine angle adjustments because I need to point out certain light reflections. So I need the angles to be ideally positioned.

 

@ Francisco: I checked the position, and all the scene is aligned around the origin point. I also toggled the active degradation and seems to make no difference.

Interesting thing: I tried to walk through while in perspective (not camera). It works! I click, drag and move (the view is following the movement) and release. All perfect. When I switch back to camera and try the same thing, the image does not follow the movement of the mouse. Instead it updates only at the release of the mouse button.

 

So, I figured that the best way to deal with this: select camera, switch to perspective mode, pan/tilt until desired angle and CTRL+C to move the previously selected camera to the resulting perspective view. I hope this makes sense.

 

Right now this solution works, thank you for your time again. If I figure something else, I'll post it.
