Change Coordinates type PREDEFINED

Hi,

i try to change my coordinates on my ImageTarget Shader.

When i use the UserDefined  type the shader UserDefinedTarget have a negativ tiling (x-1 / y-1)

Same when i use the CloudReco type the shader CloudRecotarget have a negativ tiling too (x-1 / y-1)

So my 3DModel is coherent with the "Front" of the 3d world space.

Bu when i use the Predefined type the shader xxxx_scaledMaterial have a positif tiling (x1 / y1).

So when i stream my 3Dmodel, it is in the wrong direction.

How can i change the coordinates of this shader ? ( it isn't instantiate in vuforia folders and it doesn't take the manual modifcation in play mode)

Thank you
