This is the message showing in the bottom left corner of XSI.
I know why does this msg is coming up. since. i have some pictures as textures, it kept in a list that i have a set of textures. however, some of the textures are removed, i dont' need them anymore so i kill them.
however in the record of XSI, they should be existing. that's why this is the msg coming up. The problem is, how do i get rid of those records. these msg just slow me down alot. everytime i load up the scene. or minimize then maximze the screen, it load a lost of warning sayint this.
