I tried changing to smaller images as the Asset Flow was changed from index to index, but it’s tedious to create and slow to change images. Otherwise, it works fine. I set the Expansion Factor to zero in the Asset Flow and used an image I altered in Photoshop - making the image increasingly smaller on the canvas and saving them as png files with transparency around them.
I’ve found in the past that transparent images can sometimes make up for things I can’t control in Intuiface. Good luck.
