did your export fail or are there actually differences between 3ds and clipnote studio when playing this back? in clipnote studio, there are only the flowers, not the cat.
could you check your submitted file? as it is right now, the render does not match the submission. or am i doing something wrong when importing and playing back your entry?
edit: i checked the imported .pngs and it seems like the cat was imported with white color instead of black so it doesnt appear on the white background - pls double check
