The shard pattern and animation have been created using standard MAX modeling techniques and reactor®. All necessary helpers and auxiliary collision objects are available on a hidden layer and still contain the original dynamics settings, so that you can refine and alter the breakup animation as needed.
The scene is ready for rendering using VRay. You can of course replace the glass materials with your own standard raytrace shaders, as well.
Don't miss the preview animation, which can be downloaded below!
