How does one add weakspots to a vehicle?

Personally I use skeletal mesh in combination with physics asset collisions and physical materials. Break the hit result -> phys mat + bone.

(4) Use a physical material mask (I never done this). If you hit something then you can get the physical material in the hit result. Seems that with a physical material mask you can apply several physical materials to your material. Then based on what physical material you’ve hit, you can deal different damage.

-you will need to create the textures for the mask, so setting this up will need some work
-will be most accurate in combination with complex traces [HR][/HR]
Keep in mind you don’t need to make this too accurate, only as accurate that the player does not has the feeling that something is wrong.

Ah OK so that is how you are supposed to do it, can this be done on a static mesh?

I already use a system based on what scene component was hit for determining when the weapons are hit and I hate texturing so I guess I will use suggestion 3 (I did create a system like 3 before but it would sometimes let projectiles go all the way through it without registering a hit though this was probably just me incorrectly setting up the collision.)

So I guess if the proper way involves textures I will be using the alternate way.

I don’t know whether or not it is the “proper” way, but physical materials work on anything where you apply a material. So it can be done with a static mesh. When you break the hit result -> phys mat, that will give you the physical material you’ve hit.

Normally you can only have one physical material per material (no texture needed here, you just specify what physical material you want). Since that may be a limitation, with a physical material mask you’re supposed to be able to have several different physical materials applied to one material. But then of course you would need to specify where they are, and apparently you would do that via a texture. But I never used a physical material mask.

simply put, you can add small colliders where you want “weakpoints” in the BP class, so “onhit” something happens to the vehicle
