I`m making items that can be shattered by player`s melee combat. My bp actually only has a geometry collection component and a custom component. This custom component is used to receive location of the object being hit, and to generate an FS Master Field actor at that location to destonate the chaos geometry.  
But I`ve found that setting of UseDirectionalVector for field actor spawned in a component no longer works, even Radial Magnitude could not make the fragment fly out in special direction.

If I copy these node in the Player`s Blueprint to generate the field, it `s perfectly fine, fragments can fly to the other direction of the hit. But such a trigger method is clearly not suitable for large -scale project development.

Why would field actor spawned in a custom component only disintegrate the debris in place instead of flying out? I couldn`t understand it at all. Will someone fix it in the future? 🥲

Hey there, This is probably happening because the field is spawning and firing on a single frame and the force is being applied too early. I would try setting the lifespan of the field actor to 0.1 or 0.2 to allow the field to apply velocity over a couple of frames.

Also, you might have better luck skipping the field and using the ‘Apply External Strain’ node followed by ‘Apply Breaking Linear Velocity’. This is a lighter weight way to cause a break and apply velocity
