I have a custom material, with an image texture, in Inventor 2013. When I edit the image in the Texture Editor, I cannot change the texture's offset or its tiling. Changing the Offset X and Y values under "Position" has no affect, neither does changing the horizontal and vertical values under "repeat". The only values I can seem to change are the sample size and rotation. I am new to Inventor and am probably missing something. What do I need to do to change the offset?
