# Adjust Block
These nodes shall be used to adjust the various channels of a block using Curves Float Objects.
This is really useful, especially if you need to adjust a texture (hue, luminosity, saturation, etc).
As example, let's set create a Blueprint using a photograph as a Texture and "Adjust Block HSLA"
with a Float Curve linked to the Hue as a Variable.
*Creating the Float Curve*
*Adding it as a Variable*
*The Blueprint*
By default, to respect the original colors, the curve must go from 0-0 to 1-1 :
If we change the curve orientation from 1-1 to 0-0 :
Or if we change the curve from 0-0.5 to 0.5-1 to 1-0 :
Please note you will have to check the result by stamping the brush on the canvas each time.

# Convert
This node will convert the whole Block to another format (Color Model + Channel Depth).
