I'm not seeing how what you posted is relevant, the declaration of m_angEyeAngles is fine, but no interpolated variables are processed for a spectated player if ShouldInterpolate() returns false, which it does in some cases when spectating a player in first person. I haven't tracked down exactly why since this is a simple fix, most likely their viewmodels (which are visible, the spectator target is not rendered in first person) is chain requiring interpolation and that keeps m_angEyeAngles going.

This bug is present in TF2's code as well as I've seen it there too. The issue is that the player's ShouldInterpolate() doesn't take into account if the local player is spectating this player or not, causing it to no longer have it's interpolated variables (like m_iv_angEyeAngles) processed. I've been hunting this bug for a while in my mod and finally solved it, and I figured I'd share the solution here: In c_baseplayer.cpp, go to the ShouldInterpolate() function, and add this at the bottom above BaseClass::ShouldInterpolate(): if ( GetLocalPlayer() && GetLocalPlayer()->GetObserverTarget() == this ) return true; This will fix it. Hope this helps! Note: I didn't look too much into this, but the spectating of players is done via CalcView which doesn't appear to change what render->GetViewEntity() would return - the entity returned by this always interpolated, which would seem to be the intended way for this to work, but doesn't.
