First the Glare shader is "hidden". Probable since they didnt have time to fix it in time for release. Its a bit unstable. At least for me.
You have to edit the lume.mi file located in: \3dsmax6\mentalray\include.
Make sure you save a copy of the original file just in case...
Just open in a texteditor and scoll down a little until you find:
gui "gui_Glare" {
"outputTypes" "-tag",

Delete: "hidden" + the: , (comma) in the line above. Save the file.
Now the Glare shader should be visible in the material editor.

Glare is a post render effect so to use it go to the render panel. Make sure you are rendering with MR and then go to Renderer -Camera shaders - Outputshader and click on map and select Glare.
To change the setting you have to drag it to a free Sample slot in the Material editor.
I havent got it to work with a quality setting below 3 so set it to that and raise the spread for more pronounced effect.
Using Streaks crashes Max for me so be aware...
Good luck!
