To create assets, I was inspired by the work of Vitalik Andrulis
if you work with destruction you should use this asset.
To create small pieces of earth from falling on it, I used this asset as a basis, but it greatly facilitated.
during the course of work I created an interesting constraint
which takes the main pieces before fracture and after fracture creates constraints between them one for each with the correct pivots.
I worked for a while on destruction, to speed up my work, I created a set of assets.
For garbage and a set of construins.
Here I created a procedural house and used these aasets.
I posted this scene and asses on my channel patreon.com/unitmotion
If you want to buy it
I divided the work into several options:
debris and constraints:
and a little hda for fracture wood(free):
