Shader and GUI

[disi]

Hi,

I am looking for a way to implement a slider for a variable to be passed to a shader. Or maybe just a selection of 3 or more values or a dropdown like the size of the shadow maps.

I see with the components you get the ON/OFF tick for your Mod-Shader, but I did not see any value options the other component files. Is this possible?

p.s. I do not want to mess with the GUI, just to add a slider. Only if there is some option within the shader files, to keep things together.
