I found a lot of similar questions about the Cell Fracture add-on, but all with different issues. As you will notice from the screenshots, (Blender version 2.83 LTS) between frame 125 and 126 you can see how Suzanne explodes just before the impact of the spiked ball, although she has set the Margin to 0.0001 as well as the shape has been set to Mesh and not Convex Hull. Below, following some tutorials, I also followed the advice to fix the bug of the chain that breaks, decreasing the speed and increasing the steps per frame and the solver iterations (unlike version 2.92 for example, which terms change to '' substeps per frame '').
Let me know and you need the file which in this case I will load it.
Thanks in advance.
