Distance to Meter scale

The distance scale in UE4 is 100 units = 1m.
So distance between two FVector's * 0.01f = distance in meter
(You can also use / 100.f, but multiplication is faster than division and has no problems with 0)

auto DistanceScale = 0.01f;
auto distanceInMeter = UVectorMaths::Distance(cameraLocation, enemyLocation) * DistanceScale;

Actor Array location

Like in all other UE4 games, the actor array is in ULevel under offset 0xA0.
The SDK Generator can't find it, so it's always hidden in UnknownData bytes block.
It has to be fixed manually.
Create a second UnknownData that will be placed under the actor array, change the size of UnknownData00 and add the actor array.
Caclucalting
UnknownData00 new size = AActors offset - UnknownData00 offset
UnknownData10 offset = AActors offset + AActors size
UnknownData10 size = ActorCluster offset - UnknownData10 offset

Before:

unsigned char                                      UnknownData00[0xA0];                                      // 0x0028(0x00A0) MISSED OFFSET
class ULevelActorContainer*                        ActorCluster;                                             // 0x00C8(0x0008)

After:

unsigned char                                      UnknownData00[0x78];                                      // 0x0028(0x0078) MISSED OFFSET
TArray<class AActor*>                              AActors;                                                  // 0x00A0(0x0010)
unsigned char                                      UnknownData10[0x18];                                      // 0x00B0(0x0018) MISSED OFFSET
class ULevelActorContainer*                        ActorCluster;                                             // 0x00C8(0x0008)

Get UAthenaGameViewportClient and PostRender address

auto AthenaGameViewportClient = UObject::FindObject<UAthenaGameViewportClient>("AthenaGameViewportClient Transient.AthenaGameEngine_1.AthenaGameViewportClient_1");
 
const size_t PostRenderIndex = 88;
const auto vmtPostRender  = *reinterpret_cast<uintptr_t***>(AthenaGameViewportClient) + PostRenderIndex;

PostRender hook

typedef void(__thiscall *tPostRender)(UGameViewportClient* uObject, UCanvas* Canvas);
tPostRender OriginalPostRender;
 
// Function that got called at the end of rendering, perfect to draw our overlay
void HookedPostRender(UGameViewportClient* thisPointer, UCanvas* canvas)
{           
    // our code here (Overlay, ESP etc.)
    OriginalPostRender(thisPointer, canvas);
}

Get UWord and GameInstance

auto uWord = AthenaGameViewportClient->World;
auto gameInstance = AthenaGameViewportClient->GameInstance;

ULocalPlayer, APlayerController and AAthenaPlayerCharacter from LocalPlayer

ULocalPlayer

auto localPlayer = AthenaGameViewportClient->GameInstance->LocalPlayers[0];

APlayerController

// AthenaGameViewportClient->GameInstance->LocalPlayers[0]->PlayerController
auto playerController = localPlayer->PlayerController;

AAthenaPlayerCharacter

// AthenaGameViewportClient->GameInstance->LocalPlayers[0]->PlayerController->Pawn
auto localPlayerActor = (AAthenaPlayerCharacter*)playerController->Pawn;
// or
auto localPlayerActor = (AAthenaPlayerCharacter*)playerController->K2_GetPawn();

Fonts

Two methods to get a font for engine drawing.

1. Find a font object by name

Available fonts / UFont names

Font Engine.Default__Font
Font Roboto.Roboto
Font RobotoDistanceField.RobotoDistanceField
Font RobotoTiny.RobotoTiny
Font RobotoMono.RobotoMono
Font MapFont.MapFont
Font RiddleMapFont.RiddleMapFont
Font Windlass.Windlass
Font PerfCounterFont.PerfCounterFont

To get a font:

auto font = UObject::FindObject<UFont>("Font Roboto.Roboto");

2. Get a font from the UEngine

Each UE4 game got an instance of the UEngine class with default fonts set. The UAthenaGameEngine class derives from UEngine.
Get a default font from UAthenaGameEngine:

auto font = AthenaGameEngine->MediumFont;

Check out the UEngine class in the SoT SDK dump for more fonts.
