Alright, now it's time for the interesting part: smashing the windows. We are going to deal with particle systems and there are hundreds of different ways to do this step, from using Max's default particle system to powerful tools like Houdini. It's up to you what you choose, but like I said earlier, I went for the easiest and fastest way which was to use 3ds Max. To let's use P-Array, some Bomb and maybe some P-Bomb particle systems to easily some make some customized objects, like a sphere or cylinder, explode. And don't forget to make the window explode too! Render your explosions and save the results with their mask images for each output. Don't worry about the shapes; we'll fix that in Photoshop.
Here's what I got after a few minutes of trying (Fig.06).
Now let's switch back to Photoshop and add the respective broken glasses layers, with their mask layers. Just place the right thing in the right place and use the Eraser, Stamp and other tools to create a great particle view of the glass. Please note that while I used MR Glass as the material, you can also blend these pieces together, with Multiply or Hard Light modes in Photoshop.
As all the glass is not broken in this scene, we need to keep some areas "close-to-exploding". It's simple to do this; just keep the un-broken glass on the bottom layer and add and blend a texture as I've done in Fig.07. I used a simple Cellular map in Max to create this texture.
Do what it takes to deal with the particles and you'll have something like I have here (Fig.08).
Now you might notice a problem here. As our particle crash was done in Photoshop and not in Max, the car paint is not reflecting it! So what we need to do is simply duplicate some particle layers and blend them in needed places and fake the reflection (Fig.09).
The big steps are now done, so just do the same thing for the front light (Fig.10), and then the image is completed (Fig.11)!
You can easily add your own ideas into an image like this, but believe me, crashing scenes are amazing! If you've created any, don't hesitate to let me know about it, and by the way it really helps if you listen to thrash music when creating something like this!
I remember that I sent this artwork to Criterion, the creators of the Burnout series, just wanting to share what I'd created and they replied and said that they enjoyed it! I had a very good time with this artwork, and I hope to produce more, and better, work in the future.
Here's a quick summary of some of the topics we've covered in this tutorial: post-production, adding, removing, blending, making customs brushes from your 3D outputs, making glass explode.
I hope you found this tutorial useful!
