#Blender tutorial explode how to#
I wasn't quite sure how to get an explosion to work but when I ran the game engine as a test the objects exploded simply because that's what happens when the objects are too close together in the game engine, it treats it as a collision. This meant that there would be relatively few shards created by the actual script, in the end I opted for 20 shards to be created (once enabled script appears in search menu, press T after running the script to see the options) as I wanted them to stay quite bulky. Now I knew that I could do the smaller shards with a particle system and it takes a bit of pressure off the game engine as although it can handle hundreds of objects it can be a difficult to control them, so a particle system it was to be (I'll get on to the particles a bit later, this just explains that only the main shards are controlled by the game engine). When the fracture script runs it keeps any properties the single object had and copies them to the individual shards that are created, so it makes sense to choose any settings before fracturing. Knowing that I would be using the rigid body features of the game engine I set the monkey model to be a rigid body with a 'Convex Hull' collision bounds type before using the fracture script. Having made several attempts to create the shatter effect by using a particle system I realised that my only option was to use the game engine (not one I wanted to resort to as my ATI graphics card has issues when using the game engine). After a quick scope out of the various posts on Blender Artists looking for a suitable script I foolishly realised that Blender already comes packaged with a fracture script and I started playing around with the settings to get a good result. The second part and one of the main points of the video is the actual shatter effect. Secondly I knew that I wanted the material to make it look like a jewel and luckily I had the perfect HDRI image for creating this effect courtesy of (I used the Grace Cathedral). The first thing I quickly decided on was the fact that I wanted to use the classic Suzanne model in blender as the focus was the effect and not the modelling.
