Previously I have modelled the balloon for this project, this time I created shaders for them to make 2 different colour variations. I wanted a fun fantasy look that feels dynamic, so not only I animated the movement of the balloons to rotate but also add some shakiness and tilts to them. I purposely chose glass and glossy material with the intention to make them the main highlight of the scene. On the balloon itself is a shader that I also animated in the end to make a lava lamp/lightning effect that ended up looking really cool.
