Question regarding GUI sliders

[realvision]

Thank you for the code Farshizzo.
I do think I need to read a lot more! I was thinking adding a texture as background would be a one line code :-)

I tried out your example and it does work, but I have no clue as to how to make the live camera appear as the backgorund. Simply substituting 'cam' in place of tex in the above example does not do it

Regards
