It used to work perfectly, but then in the last compile it just crashes when I hit play.
// Replace the static meshes of the tiles with instances. Otherwise the game will run like ■■■■
TMap<UStaticMesh*, AInstancedStaticMesh*> meshes;
if (UWorld* world = GetWorld()) {
for (auto tile : tiles) {
UStaticMesh* mesh = tile->GetStaticMesh()->GetStaticMesh();
if (!meshes.Contains(mesh)) {
AInstancedStaticMesh* instancedStaticMesh = world->SpawnActor<AInstancedStaticMesh>();
meshes.Add(mesh, instancedStaticMesh);
instancedStaticMesh->SetMesh(mesh);
}
meshes[mesh]->AddInstance(tile->GetTransform());
tile->GetStaticMesh()->SetStaticMesh(nullptr);
}
}
The AddInstance() function is just this btw
I’ve gone through every line of the code and the only thing that crashes the game is when I call AddInstance and it’s mesh->AddInstance(transform);

Find the log file (in Saved/Logs/ProjectName.log) and post the stack trace.

OK, so I just wanted to see the stack trace, not the whole file. As you can see the issue is:
Error: Unknown RHI vertex element type 0
Which according to this answerhub page can be solved with:

for future reference, which part is the stack trace?
