Why does the origin of my reps move when I copy them into ACS?

When you want to use a representation in ACS, the original image size, in pixels, must be in terms of powers of 2. So, for example, a square image could be 256 x 256 or 512 x 512. Rectangular images can be, for example, 256 x 128 or 256 x 512. If the original images do not conform to this rule, then, although they appear as expected in SmartSpace, when they are imported into ACS the representations' origins may be shifted or their scaling distorted.

Note: If your image does not have dimensions that conform to the power of 2 rule, you could add transparent padding to the image to make it comply.

See Copying models for use in ACS for information on importing representations into SmartSpace for use in ACS.
