How to achieve this destruction effect?

Question

I would like to do something similar at this:

youtube: Minecraft Block Destruction with Realistic Physics

I have two questions:

1. Can I handle a simulation like that or bigger? My PC is

CPU: i7-7700k 4.20GHz
GPU: 1080ti 11GB
Ram: 32GB ddr4

2. How can I set up a simulation like this? I know this is a generic question, but even a starting point would be a great answer.

Thank you for your time.

PS: Sorry for my English. I'm not a native speaker.

Answer 1

For this purpose blender user usually use Rigid Body simulation. Here is a cookbook for a cube segmented into 10x10x10 (1000 parts). Yes it is process intensive and this is just one cube. The most calculation takes Constraints.

Create a Cube

• Select a Cube
• Assign Array Modifier > Count=10 > X=1
• Assign Array Modifier > Count=10 > Y=1
• Assign Array Modifier > Count=10 > Z=1

Search for operators:

• Convert to Mesh
• Separate by Loose Parts
• Origin to Geometry
• Move to Collection > New

Create a floor

Add a Plane and search for operators

• Transform Scale
• Apply Scale

Create a simulation

With Cubes selected, search for operators:

• Active (Rigid Body)
• Change collision shape > Box
• Connect (Rigid Body)

With Plane selected, search for operators:

• Passive (Rigid Body)
• Change collision shape > Box

You can also try version of Blender with Fracture Modifier, that is much comfortable to work with, especially with constraints, but I didnt find grid cuts.
