how to make a falling tree animation

Recommended Posts

Hi

 

Your going to need to give a bit more details on what type of falling tree?  Do you want a tree that  breaks in half and falls, or a tree that falls from the roots?  Do you need the branches to be dynamic and respond to wind, and the ground?

For realistic tree fall your need a Tree, Ground, softbody dynamics, and Collision tag for the Ground.

Use Soft body dynamics tag on the tree, and  make a vertex map by using the (Set Vertex weight from the Select menu.)  Set that to 100%  You can put this map into the Mass map slot of the soft body settings.  Add a wind effector from the (Simulate/Particals menu).  Drive the wind speed up.  You need a ground so make a ground and add a collision tag to the ground geometry.  Now you need to select the vertex tag and paint either Absolute to make that area more dynamic, or subtract to remove it, you can also floor fill all or a selection of polys.  If you for instance want the tree to fall but not move from roots then select the bottom ring of polygons at the root of the tree and click on apply to selected in subtract mode.    Your need to also tweak the soft body settings such as Shape Conservation settings.  The result would be that the tree falls, and the branches flex as they hit the floor.  Your need to also adjust the shape type for both the collision tag and soft body dynamics, this is the collisions tab of each tag.  This will effect how the dynamics sees the shape and its response.

this is really complicated , can i send you the file and you make a simple one ?

plus with the sofdynamics the timeline almost freezes !

i was thinking of using splines with dynamic tag and mesh inside the tree with the spline as a cage but it didnt work very good with the ground

Here is a quick set up.  The time consuming bit it setting the dynamics settings right, and for that your need to consult the manual.

You can also try rigging the tree and use dynamic joints, but your wont get the collisions with ground you desire.
