Here is a
scene and a video of quickly switching to LookDev state.
Note that there are Scene states (Tools > Manage Scene States) and State sets (Rendering > State sets), and each of them can get confusing enough, not speaking about using them together.
For specifically having a LookDev state and mostly other things as well, I have found State sets to be more handy. Their only downside is that you need to activate and deactivate each state manually, and you cannot use them with BatchRendering (you can use Render All states, but this will be tricky to set up, and more time will be needed to check everything). Scene states can be used for Batch Rendering and generally provide more control.
State sets record changes from the neutral state - the state where no State is active. The arrow next to the state tells that the state is active, clicking on any active arrow will bring back the neutral state.
I have tried having single LookDev state with multiple environment maps using lightmix, but this is really not handy and you kind of lose control over the lightmix, and that is something you may want to keep intact.
So I have just recorded environment changes (one in real environment in 3ds Max, the other one as Render change, switching to "Use Corona" for environment map) and viewport being perspective instead of in Camera, so you can freely move around and look at the object.
So, for just having a quick material check state in the scene, the idea is to:
• isolate the object
• have no hidden light rendering
• just toggle the LookDev states
Each of them in the attached scene has just one environment map, one for studio, pure white lights, the other one an HDRI which a few years back used to have well balanced colors and values.
This should work perfectly in your case.
Of course much more and much complex things can be done with State sets, let alone combining them with Scene states.
