Question about IfcImageTexture

[Scarmentado]

Hi Team !

In the following code, I manage to render an IfcSurfaceStyleShading (with a color) but when I try an IfcImageTexture my object disapear, Sure I missed something ! :)
If you could help me ...

using (ITransaction txn = mVarIfcStore.BeginTransaction("Create Point"))
            {
                // Position Zero.
                IfcCartesianPoint myZeroCartesianPoint = mVarIfcStore.Instances.New<IfcCartesianPoint>();
                myZeroCartesianPoint.SetXYZ(0, 0, 0);

                // Position.
                IfcCartesianPoint myLocationPoint = mVarIfcStore.Instances.New<IfcCartesianPoint>();
                myLocationPoint.SetXYZ(location.X, location.Y, location.Z);                

                // Une sphère.
                IfcSphere mySphere = mVarIfcStore.Instances.New<IfcSphere>();
                mySphere.Position = mVarIfcStore.Instances.New<IfcAxis2Placement3D>();
                mySphere.Position.Location = myZeroCartesianPoint;
                mySphere.Radius = new IfcPositiveLengthMeasure(200);

                // Un cylindre.
                IfcRightCircularCylinder myCylinder = mVarIfcStore.Instances.New<IfcRightCircularCylinder>();
                myCylinder.Position = mVarIfcStore.Instances.New<IfcAxis2Placement3D>();
                myCylinder.Position.Location = myZeroCartesianPoint;
                myCylinder.Radius = new IfcPositiveLengthMeasure(20);
                myCylinder.Height = 300;
                
                // L'union des deux.
                IfcBooleanResult myBooleanResult = mVarIfcStore.Instances.New<IfcBooleanResult>();
                myBooleanResult.FirstOperand = mySphere;
