[Closed] SDK-C# Set transform controller value

Is this working for you?! which Max version do you use? not working for me. I have 2020

I tested on Max 2018 – 2022 and none of them is working. I can build and max will not crash, but nothing is changing in the scene.

It’s 2016. And no, nothing is changing in the scene. But the same with your code.
It was just to try something without ‘ExecuteMaxScript’.
Sorry.

have you tried setting the sub controllers (position rotation scale) from a decomp_affine of the transform matrix ?

virtual Control *  GetPositionController () 
virtual Control *  GetRotationController () 
virtual Control *  GetScaleController () 

CoreExport void decomp_affine ( Matrix3 A, AffineParts * parts )

where

struct AffineParts: public MaxHeapOperators {
	/*! The translation components. */
	Point3 t;	/* Translation components */
	/*! The essential rotation. */
	Quat q;	/* Essential rotation	  */
	/*! The stretch rotation. This is the axis system of the scaling application. */
	Quat u;	/* Stretch rotation	  */
	/*! The stretch factors. These are the scale factors for x, y and z. */
	Point3 k;	/* Stretch factors	  */
	/*! Sign of the determinant. */
	float f;	/* Sign of determinant	  */
	};

from my first post

Control *c;
c = node->GetTMController()->GetPositionController();

Something like this?

private IMatrix3 GetTMControllerValue(IINode node)
{
    int time = coreInterface.Time;
    IInterval interval = globalInterface.Interval.Create();
    IControl tMController = node.TMController;
    object rotation = globalInterface.Quat.Create();
    tMController.RotationController.GetValue(time, ref rotation, interval, GetSetMethod.Absolute);
    object position = globalInterface.Point3.Create();
    tMController.PositionController.GetValue(time, ref position, interval, GetSetMethod.Absolute);
    object scale = globalInterface.Point3.Create();
    tMController.ScaleController.GetValue(time, ref scale, interval, GetSetMethod.Absolute);
    IMatrix3 matrix = globalInterface.Matrix3.Create();
    matrix.IdentityMatrix();
    ((IQuat)rotation).MakeMatrix(matrix, false);
    matrix.PreScale((IPoint3)scale);
    matrix.Translate((IPoint3) position);
    return matrix;
}

private void SetTMControllerValue(IINode node,IMatrix3 matrix)
{
    int time = coreInterface.Time;
    IControl tMController = node.TMController;
    IAffineParts apmatrix = globalInterface.AffineParts.Create();
    globalInterface.DecompAffine(matrix, apmatrix);
    tMController.PositionController.SetValue(time, apmatrix.T, true, GetSetMethod.Absolute);
    tMController.RotationController.SetValue(time, apmatrix.Q, true, GetSetMethod.Absolute);
    tMController.ScaleController.SetValue(time, apmatrix.K, true, GetSetMethod.Absolute);
}

it works in some cases, but it will crash on this line:

object scale = globalInterface.Point3.Create();
tMController.ScaleController.GetValue(time, ref scale, interval, GetSetMethod.Absolute);
