FSXA object disappears

A friend places an object he made. aproach or move away the object disappears. 2 large texture sheets one that has everything that disappears is in one texture sheet. Perhaps the color of offwhite he used. I've heard of this before but can't remember the possible answers.

Placed with IS3 for FSX. Everything shows when placement file (object file) is active). Before we all go blame IS3 again..... I took his object and textures and placed it with ADE.... result.... same thing.

Anyone want to take a W.A.G. at this? Bob
