fatal error C1083: Cannot open include file: 'Px.h'

I was able to follow along with the thread, and also realized that I could add “PhysX”, “APEX” to my Build.cs. After that, though, I’m running into “unresolved external symbol” for ‘UPhysicsSerializer::SerializePhysics’ and ‘UPhysicsSerializer::CreatePhysicsData’ functions. For some unknown reason, I can’t figure this one out.

I’m working on making some changes to UInstancedStatisMeshComponent, which calls those two functions. Even though I’ve added PhysX to the build, and all of the includes don’t give errors (included the same .h UISMC uses), I can’t seem to get this unresolved external symbol to go away.

My understanding is that the most likely cause is the Definition for those functions isn’t linking for some reason, but I don’t really know why. It all seems to be under the “Engine” module, so I can’t think of why this is happening. Especially since I’m using the same function (only needed it to not be private) and includes. Every line should be exactly the same character for character.

Any thoughts?
