I've just begun to model and I was following a tutorial and when I try to use a random Death Star texture for my object it it red and says "Invalid Argument Specified." Here are the steps I took to get here:
Made my model, merged the pieces, duplicated that and called it collision and unchecked render visibility. Then I duplicated that, named it doorway_lowrez, and checked the render visibility box. My collision and doorway_lowrez are under MS3DSceneRoot. I then select doorway_lowrez, leftside, rightside, top, and polymsh(the merged version of rightside leftside and top). I then click Material->Phong and select the Death Star texture. When I click on it before I press ok it shows up with a red border and then when I click it I get the specified message above.

With SoftImage|XSI 7.5.

Try this or this tutorial. You don't want to name the null MS3DSceneRoot, name it Dummyroot. MS3DSceneRoot was used for BF1.

Pandemic didn't use MS3DSceneRoot for anything in SWBF 1 or 2, this was just something used by those guys who wrote that tutorial. You could probably name the master parent anything, but there is no advantage to straying from DummyRoot and there just may be underlying consequences from using different naming conventions that we have not yet discovered, just stick with what works to avoid potential problems.
