I’m using the blueprint first person shooter as a base and currently experimenting with changing the projectile properties. I’m trying to change its mass, which I believe is calculated by the engine based on the mesh of the object and the physical material applied to it.
Starting with the MyProjectile blueprint I went through each component looking for physical material, but they were all set to none. I then tried digging through the mesh itself, and then the material applied to the mesh, and then that material’s parent. Eventually ending up at M_Template_Master. But nowhere along the chain was physical material set.
I believe what your looking for is in the Components section. Click on the Sphere under the Components tab, go to the Physics section and click the drop down Arrow. It contains settings to adjust Mass.
As far as the Physical Material, you are right. This particular mesh doesn’t have one. All of the characteristics that allow it to interact with the world are handled through the Event Graph.
Hope that helps, post back if you have any other questions.
A Physical Material isn’t required on every physics object, it just allows for more advanced physics controls. All of this Projectiles physics settings are either created/tweaked through Blueprints or inherent through UE4’s default physics settings located in the details panel.
Please take a look at this documentation for more info on physical materials.
