Normally Panel is a collection of scripts that take out some tedious parts of Normal Map editing in Photoshop.
Instead of having to rebake your Normal Map just to get it rotated, or having to do the channel swapping yourself, let Normally Panel do that for you.
Normally Panel contains buttons to do 90 degree turns (CW and CCW) as well as with green channel inverting while doing the turn, Inverting the green channel, a 180 degree turn and 2 different ways to do Normal Map blending
NM Blue will toggle Overlay and turn the blue channel off of the layers or group of layers
NM Blue 2 will change the blend mode to linear light with 50% opacity, put a color overlay(255,255,128) with a blend mode of linear Burn and blend the interior effects as a group.
Quickly work on your Normal Maps with less hassle :)
