How to use Rigid Body Dynamics in Blender 3D 2.50
The new interface and tools of Blender 3d 2.50 will make the learning process for new artists a lot easier, but in the other hand a full change on the interface may confuse old users at a first glance. I my Blender classes, one of my students asked me how to use Rigid Body Dynamics in 2.50. By following the same panels from Blender 2.49 the Rigid Body options should be placed right next to the logic bricks. At the new windows organization in Blender, we will find a window and not a panel called Logic.
In this window we will find the logic bricks and the properties for objects used on the game engine.
With a quick look around you will notice that the Rigid Body option is missing. Where is it?
After a few minutes I figured out the way to get into the new Physics options in the Game Engine. Before anything, we have to change the render type of Blender to use the Blender Game. If you use the Blender internal render, only the options related with Blender physics will be available. Rigid Body Dynamics is associated with Game Engine.
Change the output render at the top of the interface. I hope that an option to export directly for YafaRay or LuxRender is available in the future, besides POV-Ray.
When the Blender Game is selected, go to the Physics panel and we will find an option to choose Rigid Body Dynamics!
The rest of the setup works just like in Blender 2.49, with options to set collisions and the mass of the object. Now we can reproduce the domino tutorial, using Rigid Bodies in Blender 2.50 as well. The only thing I couldn’t find so far is a way to bake the physics simulation as keyframes. But for real-time animation it works fine.
Even for architectural visualization artists, it’s important to know how to use the game engine, because from time to time a project may be presented as an interactive presentation. This is a feature related with animation, but the scenarios used for those applications may require a few physics simulations. Anyway, it won’t hurt to know a bit more.
