I want to animate one left and one right door within the 3d cab. The door opens but does not stay open. I opens and closes immediately. I want the door to stay open, because the loco runs with open doors quite often. The *.cvf file looks this

TwoState (
Type ( RIGHTDOOR TWO_STATE )
Position ( 175 363 61 31 )
Graphic ( "" )
NumFrames ( 2 2 1 )
Style ( NONE )
MouseControl ( 1 )
)

the animation in the *.s file is this

anim_node RIGHTDOOR:0:0 (
controllers ( 1
tcb_rot ( 3
slerp_rot ( 0 0 0.3478272 0 0.9375587 )
slerp_rot ( 4 0 -0.028217 0 0.9996018 )
slerp_rot ( 8 0 0.3495827 0 0.9369055 )
)
)
)

How can I stop that animation and second question: Is there anywhere info about the lines in the *.cvf file, which are necessary for OR and which can be deleted?

I believe midneguy is able to correctly animate 3D cab doors. You could PM him.

Thank you. I did PM him.

If you wouldn't mind, I'd like to know your solution when you come by it. Does operating the door with a cab control solve the problem where the door uses the whole scene's total animation length? That alone is enough of a reason for me to not animate doors or wipers, because I need a whole lot of frames for smooth brake lever animations, and most users don't want doors or wipers that take a minute and a half to cycle.

You might download the " Mason " locomotives and take a peek at them to see how they work . Their doors work very well , reasonable speed , stay open or closed .
Just a thought !

Could be you have one too many frames of animation. It is so long since have done a 2 step action animation.....

Think,

frame 0 (key frame) = door shut,
frame 1 = door open.

Something like that.

Cheers Bazza.

On my model, Frame1 is door closed and Frame4 is door open position as the Blender exporter uses 1 frame = 1s convention, however it may be different for other program...

[Hannes44]

Thanks for all the input. Problem solved: I simply removed the third frame of the animation. Now the doors open with reasonable speed and stay open, until they are closed again. @ErickC its a simple small diesel so I need only 8 frames max, but I'm building a steamer too, with 28 frames max atm. When I'm ready to build the doors I'll post again.

The problem is that smooth animations on the automatic and independent brake handles require much more frames than that - I'm using 100 - and the door has to cycle through all 100 to be fully "open" and then all 100 again to close. This makes opening and closing the cab doors a three-and-a-half minute process. This is also true of the wipers. I was wondering if this technique of controlling it as a two-frame cab control might change things somewhat. Ideally, they'd let us control the door animation length in either the CVF or ENG file.

[Hannes44]

I tried 2 different approaches for the doors. For one door I used the full 8 frames, animation is slow, but on the verge of acceptable. For the second door I used 4 frames only, animation is good, but you can't open, close door a second time immediately after the first time, you have to wait a little bit, for the empty animation to finalize. Not an ideal situation.
