Biped - Mixer (MaxScript - SDK - C#)

[MehdiZangenehBar]

When I load an animation in to the mixer, I have couple of problems.

1)  (biped has no animation ) When I load the first animation. it will transform to where the animation was saved. is it possible to bring it back to the started transform?

2) When I load second animation, the antire animation moves to the origin, will (start from origin)

3) At mixdown phase, if any part of the biped dons't have any keyframe at zero frame, mixer will add unwanted keyframe for each frame.

provide MXS code and a sample scene (scene setup) to help reproduce the problem.

Please find the attached max file and script that shows the problem.

The In-Place problem seems to be solved by updating Mixer:

(
	bip_001_controller.mixerMode = off
	bip_001_controller.mixerMode = on
)

There may be a better solution, but the idea is the same - update Mixer somehow.

1. Or we can expose some missed invalidate functions from the SDK. As my coding pipeline is C#, this problem dosn't have high priority. 

[denisT.MaxDoctor]

Set initial position for the biped character we can in MoveAllMode, for example:

(
	bip_001_controller.moveAllMode = on
	in coordsys world 
	(
		rotate bip_001 (eulerangles 0 0 45)
		move bip_001 [-40,40,0]
	)
	bip_001_controller.moveAllMode = off
)

I don't see any "mixer validation" methods in the SDK... maybe there is some ... 

I tried "UpdateDisplay", and it doesn't help in our case.

IMXtrack::ComputeTransClips() doesn't work for the solving "In-Place" issue

IMixer::InvalidateRawMix() does do the job! 

[MehdiZangenehBar]

Calling ComputeTransClips is nessecary when you need to get clip's data.

Yes we can move it in moveallmode, but the problem is how we can align it correctly.

in our case, can you save position and rotation of the biped 001 and then bring it back to the initial position and (rotation)?

[MehdiZangenehBar]

After so many fail attempt to align biped to the the initial place, I just realized there is some roles to do that:
- Biped COM should be selected.
- Horizontal and Vertical track for the move and Turn track for rotate should be activated.
So my function looks like this:

        void Begin_MoveAllMode(IIBipMaster iBipDriver)
        {
            IINode com_node = iBipDriver.GetNode(13, 0);
            core_interface.SelectNode(com_node, true);
            iBipDriver.TrackSelection = 7;
            iBipDriver.BeginModes(BMODE_MOVEALL, 1);
        }

        void End_MoveAllMode(IIBipMaster iBipDriver)
        {
            iBipDriver.EndModes(BMODE_MOVEALL, 1);
        }

any idea?
