Generally, any processing should be done in the render tree, in unclamped floating point, and image clip effects should be avoided.
Gain simply means "multiply", and offset means "add". You can use the Color_Math_Basic node to apply either or both of these transformation. The color sliders for 'input 2' are used to enter an individual factor for each channel. If that number must be outside of the 0..1 range, simply type in the values in the edit control of the color slider.

Subject: trying to find a corresponding parameter from Maya to XSI...
hey guys
working with some great artists that use zbrush and maya, and I am trying to map some maya parameters in xsi properly.
in maya there is an alpha gain and offset parameter that exists on the "image" or "file" node in the hypershade. i am trying to find the corresponding parameter in XSI. there is a gain parameter in the color correction when you enable effects, but i am unser this is actually the same.
anyone have any insight on this? I am trying to match the quality of displacement that our artist is getting in Maya, so far i am off by a small amount
thanks
steven
