How to rotate DynamicTexture by 90 degree

Hi there,
is it possible to rotate a dynamicTexture by 90°?
With UV mapping i’m able only to flip it vertical or horizontal. The porpouse is to attach a text on box only on a face but with 90° rotation.
Is it possible?

textureGround.wAng = BABYLON.Tools.ToRadians(90)
Example -

Thank you! I had tryed all the other param except W angle :smiley:
