Hi @SkaterDad, thanks for your words!
If I understand well you mean the ghosts flying to the pipes. It’s quite simple. I have prepared a png with the image of the flying ghost with no deformation. I have a model with this texture and a mesh that is just a rectangle with two parallel sides divided in many segments (64). This model uses a material whose vertex shader deforms the model into a bezier curve. You can take a look at this post
for some details.
This is the basic idea. However to move the ghost along the Bezier curve I have a slightly modified vertex shader squeezing the texture into an arc of the curve. This arc is then moved on the curve.
If you need more info please let me know. I am happy to talk about this.
Ciao!
