Q

how to animate a scene like this one?

If you asking how they did this then this is what I think

This is just animation no rigging. I would say he made all the meshes then scaled them up and the moving vines were more likely done by using a curve and a curve modifier. the grownd braking I’m not 100% on that one. more likely he had a mesh and used a cutting tool to cut it up to look like something would brack it and moved the rotation point to the ends and rotated them the way they need to move. The grass or what ever it is over the vines he might have scaled them up. Now that is what I think they did but I don’t know

Thanks, but how to add growing branches to a tree or change the shape of grass with growing ??
