Marque,
Within XSI the tif's alpha channel is being used to control the
transparency of the texture. What you are looking for is transparency
map for the object. To do this, within the render tree, plug the texture
you wish to use for transparency into the transparency factor of your
illumination
node. It sounds like you need want to invert the alpha you are using for
your tif and use that as your transparency map.
There is a good example of how to use the render tree for transparency
within the XSI tutorials. I would higly recommend starting there because
the render tree can be tricky at times.
