I cannot get this to function at all and I would love to know if its possible and if its not then why it isn’t possible.
I have an opacity mask which for ease of use is 4 separate masks wide by 4 high, so contains 16 individual masks. I then use TexCoord with UTiling: 0.25 and VTiling: 0.25 and shift the area of focus/choose which mask via two parameters.
How can I use a CustomRotator so that the Rotation Center is always at the center of my “selected” mask instead of the center of the entire sheet?
