Multiple Mats on Links and Pipeline?

Hello All,
I’m sure this is a simple issue, but it has me confused anyway. :confused:
If you’ve seen the “grass/wind” .blend file from the big buck bunny project you can understand right away. There’s “two” Mats on the Links and Pipline. Yet I cannot seen to re-create this affect! :eek:
I can see from the outliner that two materials are being applied to one object, but I don’t see how that’s possible from the Materials menu…

When I do it it only shows one, obviously…

FYI: Still using 2.49b.

That’s because you don’t set it from the Materials menu but from the Editing menu.

Thanks! I figured it would be something this simple. :smiley:
