As of late, I've been a bit bothered by my material preview's brightness. I do not remember having these issues prior to 1.6, but I could be wrong.
In any case, my problem is that bright materials look burned out easily. The material in the attachments is a material without reflection, and the diffuse value set to RGB 180. The second attachment has a Threshold of 255 applied in PS to show which pixels are completely white.
Max's gamma set to 2.2 (+ affect mat editor).

I'd like a "VFB exposure settings apply to mat editor"-button, or something. Or maybe I'm just missing something here...

+1 i Agree///
It seems to me that in previous versions of Corona it's been more correct///
Or may be this because max versions///
Brightness of all materials in mat editor does not match to  rendering brightness material in VFB with default settings //

Solution
float mtlEditor.lightsSize = 1.5

The CoronaLight in the MEdit will be bigger = more Areashadows = less burned  spot

I've kinda asked a similar question before but cant there be an option where your material preview's light, could be the exact light you have in the scene.
This would make material creation a breeze as everything can happen in the editor and you have a much more accurate idea as to the look of the material
in the current scene

How would that even work ?

Let's say I have Sun&sky system, but I am rendering interior. The material editor will be Sun&Sky ? Or resulting studio probe from interior ?

If I have camera/framebuffer exposure compensated to lit interior, the material editor would be ultra bright, since the difference between outside Sun&Sky and my interior will be huge, up to 6 EVs.

The material's look in scene is always result of actual position in geometry affected by surrounding light at that point. Your idea would require to bake that point into a probe that would be used as HDRi in way probes are used for local reflection in real-time engines.

Imho solution is just to use custom hdri inside mat editor to define whatever base look you prefer for look development.

In general, I like how the mat editor preview "scene" looks. I would just like a an EV slider, to adjust the brightness. Or possibly a light lister of sorts. Changing the color of the mat editor lights would also be very useful.

Looked into Cecofuli's solution, and found an old post by Ondra.

Now using
float mtlEditor.lightsIntensity = 0.75
float mtlEditor.lightsSize = 1.25

and it's working pretty well. :)

Something definitely changed from 1.5>1.6 (or maybe 1.4>1.6, can't be sure). It's quite off-putting with the current matedit overexposure. Is there a reason this was changed? Can we not have it back as it was?

also noticed the material preview blowing out a lot more, I'm not sure when this happened but I don't remember it being like this.

I might try that bit of script to reduce the intensity.
