Now I tried using softbodies and things of that nature but they really don’t work they kind of destroy the mesh. How do you simulate a disaster like a huricane which falls and destroys. For example wind that destroys and blows away buildings and structures still knowing that there is wind. How do you do that?:spin:
Movies that have these effects usally do it the hard way. With a little bit of simulation and a lot of tweeking and animating. So you manually model the fragments etc. This is too slow (Well not always) for every piece of debri so some automatic process is used as well with say the physics engine. Or like the explode python script. Something like that anyway
But long story short. Very slowly.
Or do a physics simulation, using the game engine and converting it to an animation. Don’t remember the details of it, though, but it would allow you to have things (any number of modeled objects) flying off in a particular direction.
What do you mean I haven’t gotten to the game engine I have been so preoccupied with animation and modeling that game engine I can hold off to later.
SO how do I do it?
You could 1) wait for the “Destroy Wooden Structures Button” in Blender 16.25, or you could 2) use the time to learn some animation techniques. Have you actually looked at hurricane footage and analyzed just what is going on? If you did you’d realize that what you’re asking for requires a lot of work, time, and many different animation skills. No one’s going to tell you how to do it all here, it would take an entire book. Start small - maybe try making a palm tree bending in a strong wind. You’ll find even that’s not so simple.
Agreed, even in film most of what you see is only done tho make you think you saw it. There’s a lot of camera shake, distortion, fake angles, quick focus on small features of the disaster without actually showing the big picture. And most of the tension, the scary, impending force is in the lighting and the sound and a good coordination between the two.

Google for tutorials with the keywords “blender 3D”, “game engine”, “simulation” and the like. I think you should find something (I actually found video tutorials of this, but I do not remember the URLs).
Ok I probably won’t try it now but soon but anyway are you sure I can use the game engine to render a huricane. I always thought you’d use the game engine for games.
It does physics, like things hitting each other and bouncing around (the typical example is making a simple sphere trigger a domino effect in a bunch of cubes). You simply ask Blender to run the effect and bake it into a non-game animation. It is a bit funky, but it seems to work very nicely.
Hi !
Here is a copy of something I have posted somewhere else on the forum.
It is not about natural disasters, but could give you some ideas around the way that you could use the Bake feature of the Game engine to animate all kinds of objects in a natural way, using forces and gravity.
Cars accident with bullet physics
Hi !
I have done some trials using the Bullet physics for simulating cars accidents.
The best way seems to use very low polygon objects for the physics simulation, matching the external shape of the real detailed objects.
You can tweak the animation by deforming some parts of the low poly objects to get the right behaviour you need.
For example, in cars accidents, you can choose which car will pass over the other one by modelling a sort of “springboard” on the front of one of the cars mesh. This Springboard will not be visible in the final rendering.
Obviously, you will have to set your objects Bound to Convex Hull Polytope. This setting gives slower computaion but is very accurate.
Parent the High definition objects to their low poly double,and put the high poly models on a separated hidden layer.
When the simulation is recorded Into Ipo curves, then switch the layers. This way, you can preview and render in high quality.Using this method, you can get trash cans hit by cars “flying” in a very realistic way.
Philippe.
What do you mean?
