Vray Camera sometimes move by itself...

[jstrob]

I often get this bug in many different scenes.

It's always only with vray camera. Sometimes I try to select something in the vraycamera view and suddenly my camera is moved randomly in space to another position. It's very difficult to reproduce. Have anyone experienced this?

[jacksc02]

I have had this in the past and its usually to do with the camera position being too far from 0,0,0

[voltron7]

I've had this happen, too, and even when the entire scene and camera was pretty much at 0,0,0
It doesn't happen all the time, but when it does, it's very irritating.

Edit: It also was happening when de-selecting an object while in a phys camera view...
Edit: I still have not had this happen since upgrading to max2011...maybe it's a max9 problem?

Have this problem in max 2008

I'm convinced it a graphics driver bug/issue ...very random & impossible to reproduce.
Closing & opening max seems to fix the problem for me.

Hope this helps

Okay, this just happened a minute ago on max 2011

FWIW I have never experienced this problem with standard camera...

Is there anything special about the camera? Is it linked to something? Is it targeted - if yes, does the target move with it?

Best regards,

Nothing special, very random. Usually it's a targeted phys cam, but it probab;y has happened with non-targeted, too.
Never took a note on which part of the camera moved, but I think it's the camera not the target because if it was the target it might be easier to correct...
I will try to make a note of which moves and in what manner next time it happens...
thanks

i am facing a different issue with vray phy cam, after setting angle in perspective i usually create vray cam & use ctrl+C to set it from perspective , but in vray 2.0 when i do this, camera flips upside down! with max default camera there is no such issue..

I've had that before but always blamed it on my SpacePilot. It can be a problem for animations. Mind you, I've had other weird things happen with my PhysCams, non of which I could entirely resolve...

This could happen if the camera target is closer than the default lens focal length. In any case, if you have more specific reproduction steps, please post them here.

yes i got this later, thanks Vlado! still curious to know why this was not happening with max default camera in same scene?

I also have a spacepilot and can confirm this was happening to me before I ever purchased the spacepilot...

[jstrob]

I have a spacepilot too... And I I still have this bug in vray 2 SP1 (2.10.01) in max 2012...

we also use a spacepilot and have problems with moving cameras.
to fix the cameras we set the Link Info Locks, that helps.


Here is a small script to use it in Quadmenu:
--------------------------------------------------------------
macroScript gantmxs_locks buttonText:"Locks" category:"gantmxs"
(
on isChecked return (if selection.count != 0 then (((getTransformLockFlags selection[1]) as array).count != 0) )
on execute do
(
for s in selection do
(
if ((getTransformLockFlags s) as array).count != 0 then (setTransformLockFlags s #none)else(setTransformLockFlags s #all )
)
)
)
if menuMan.registerMenuContext 0x7d543178 then
(
local quadMenu = menuMan.getViewportRightClickMenu #nonePressed
local menu = quadMenu.getMenu 2
local testItem = menuMan.createActionItem "gantmxs_locks" "gantmxs"
menu.addItem testItem -1
menuMan.updateMenuBar()
)
