It does not store the supplied pointer in `stdGetCurrentCamera2`; that getter returns a Terrain global populated by selector `8` during Terrain initialization. +`Terrain.dll!LoadCamera` adds a separate factory-side contract. Its GOG entry +at RVA `0x4EBE0` is `__stdcall` with four machine-word arguments, allocates +`0x1A4` bytes, calls the constructor at RVA `0x4EC60`, and returns the interface +at object offset `+0x134`. The constructor passes arguments 3 and 4 into base +initialization at `this + 4`, writes argument 3 to `this + 0x138`, and calls a +helper at RVA `0x4CEF0` with arguments 1, 2 and 4 plus `this`. Argument 1 is a +mode string: only `REFLECTION` and `REFLECTION_SHIFTED` produce a non-zero mode +value at `this + 0x1A0`.
