This is my problem:
I want to apply to a texture (taken from the webcam) a filter that convert the texture from color to grayscale.
I can’t understand how to do this. Can anyone suggest me the appropriate nodes to make this stuff?
I hope you can help me.
use this pixelshader from … uhm … i forgot sorry.
and place it into your effects folder
then open it and connect the webcam to the texture input. with ‘value offset’ to zero you will hav ea greyscale - pic
HueSaturation.txt (6.9 kB)
i took the liberty to post your shader in contributions with a help file
