Please don't use caps lock ;) Normal text is so much easier to read.
Yes, the lights converter seems to be broken and needs to be fixed
About your gamma problem: Seems like Gamma correction is disabled or set to 1.0 since your material previews are not gamma corrected (too dark).

No, it's not a texture problem, it's a max settings problem you got there. You won't get realistic results if you're not using max with proper gamma settings - even worse if you correct your textures like this!

Your gamma/Lut setup should be looking like the image attached (if you're using max 2014, for earlier versions set in- and output gamma to 2.2 too!)

I can't understand which parameters i should modify for control gamma. (a6, max2014)
Now i found inner Coronas gamma parameter, in f10.

If i understand right, to change gamma to 1.0. I should change gamma to 1.0 in Gamma/lut settings window (or switch off it), and set 1.0 in corona settings.

But when i do this, material preview still looks very bright... It is some bug, or i just cant understand something?

According to official Coronaut philosophy, you should use gamma 2,2 EVERYWHERE and never change it.

In max 2014 enable gamma correction and use gamma 2,2.

Yea.. thx.. I see, preview looks normal with all 2.2.

But what about normal maps or bump (or something like that), should i change something when i load it in material editor, or gamma correction not spoil this one?

Looks like Corona takes care of it automatically.

CoronaNormalMap is taken care of automatically. bump maps are not implemented in corona and therefore you need to override their gamma to 1.0
