1. First of all you if you want same result as mine, you must change units to generic( customize menu>unit setup)
2. Create Chamfer Box and use settings from picture
3. Picture below says everything, just make shore that boxes don’t touch.
4. Copy all 8 boxes and move them right so you can get some like this.
5. Final result of one side of the wall should be like this.
6. Copy this side of the wall, after that go to mirror option and make shore that you check no clone, and Y axis. Then, place copied wall side like in this picture.
7. This is final result. It is VERY important that you select all boxes and move them a little upward so that they don’t touch base grid line. This will keep away trouble in reactor settings.
8. Now create smashing ball and place it like this.
9. Turn AutoKey and go to frame 2. Move sphere like this.
10. On the left side pick Create Plane, and click in viewport wherever you like.
Now select all objects, including reactor plane and pick Create Rigid Body Collection.
After these two steps select all objects without sphere and pick Create Fracture.
11. Now When everything is done go to Utilities, click on reactor and follow this settings.
12. Go to Properties and assign masses to all objects: Bricks-65kg , Planks-38kg, Sphere-500kg.
Before creating final animation you must select sphere and check unyielding in properties rollout, after that go to Preview and Animation and click on Create Animation. You noticed that all bricks moved, we must erase that frames. To do that go to frame were everything is stilly and delete all frames( of all objects) from that point to the first frame. Be shore that you don’t delete sphere frames from step 9. that we made. Now is everything ready to again click Create Animation.
13. Place two VRay lights like this: left multiplier is 5, and right is 3.
14. We are now going to assign motion blur. To do that go to Rendering menu and pick Effects…
15. Environment and Effects is now open. Click Add button to assign effect. Chose Motion Blur. Leave value 1, but of course you can change it as you wish.
16. These are basic render settings for the scene.
