its a 3d model(just modeld the flat visibile areas) and the grow is animated in this model. with the help of unity shaders it look from stage to stage very smooth
very cool! thanks for answering! looks really good and couldn't tell it was 3D but that makes sense.
what do you mean by flat visible areas?
in editors like blender its not a full body, its onnly the visibile part, like bending a picture
