Nuke Tips: Customer build Nuke LUT profile for viwer

First of all, big thanks Matt from Foundry to this>>
Nuke's default LUT for monitor and viewer is sRGB, if you want to set LUT to gamma 2.2 like Shake linear comp workflow.
1: Go to Nuke Root setting, pick LUT and create a new LUT profile and you might name it ex: "gamma 2.2" .
2: right click on the new curve> Edit> Edit Expression>
3: type pow (x, 2.2)
4: then set viewer/ monitor to new LUT profile to gamma 2.2
