I don’t think that I’ll need to see the content through the droplet, so only the front face would need to be created. The moving images won’t need to be seen behind the droplet but they will need to look like they’re disappearing behind it around one side, with other images appearing from the other side. I’m a bit unsure how to apply a matrix in this case. I can see why tracking the droplet makes sense as it would ensure that whatever layer is above it conforms to the appropriate position, but I’m not sure how to apply a semi 3d layer over the top, nor how to have a still image move over it. Sorry for sounding a bit backwards.
