Realtime armour deformation

I’m interested in creating a system for real time deformation of metallic armour. Bullet holes, exploded and torn holes, etc.

Does anyone know of any examples I can look at and study to learn from?

It depends how you want to deform your armor?
Do you want random deformation or a specific kind of deformation or do you want to react to hits?

A simple form of deformation would be to replace the texture of your armor at runtime.
For example replacing the basecolor and normal maps with simple “destructed” textures.

Or, of you want to have a more sophisticated approach, look at rendertargets.

There’s also Flex if you’re after something more elaborate and realistic:
