It seems that these python script is not working…

RenderTexture.BeginChange( Rhino.Render.RenderContent.ChangeContexts.Program )
RenderTexture.SetParameter( “rdk-texture-rotation”, math.radians(90) )
RenderTexture.EndChange()

is Bug or my mistake??

If anyone knows the reason could you teach me?
I am using Rhino 7.23.

Thank you !
