The cutscene at the beginning of the first Felucia stage where Shaak Ti is telling Maris to hide. Maris walks up to her, with her back turned toward the camera. You can definitely see butt crack and her butt looks bare but it only goes down so far. They talk face to face, and then when Maris turns and runs into the forest, it looks like she's not wearing any pants! But then it shows the front for a bit and she's wearing pants! At first I thought that she was wearing one-sided pants, but later when you fight her she is definitely wearing full pants. I can't help but think it was just an error with the texture on the polygons, but it could have been intentional.
Got me all hot and bothered though cause I think Maris Brood is the hottest chick in this game! I don't even like the way Juno looks.
