Hey guys, This is an animation of a rose blooming I made in blender. It was rendered in Cycles at 100 passes per frame (about 2 minutes). The total render time was around 8 hours.
The whole animation was driven by a lattice modifier and shape keys. After I finished modelling the rose I added a lattice modifier over it all. I then added a couple shapekeys to the lattice so that one was a half closed rose and the other was the full bloom. After adding a few key frames to the shapekeys the animation was complete. The stem also used a shapekey as well. At first I was just going to do a still render of the rose, but then decided it would nice to have a little bit of movement going on.
