This week I got back to those grass/tree wind animations that I had a little trouble with last week. After much deliberation on how to do this without a mesh deformer, I resorted to simply giving each grass bushel and tree a subtle rotation animation. The trickiest part was setting each object up so that it would pivot at a specific point rather than at its center. Thankfully, that much was resolved by putting each tree and grass bushel under another game object – ‘windblower’ – which would determine the pivot point for the child object. The animations can be seen below:
Up next! More subtle environmental tweaks like the ones above.
