It is strange you have the first one ok and when you load the liveries you have all white. I think is because you don't have enough VRAM in your video card memory and loading a second livery overloads the video card. Even your first problem with objects not appearing and when you disconnect pixel shader let me see that you don't have a strong video card. Or you don't have good drivers for it. I suggest (if you didn't do it) donwload and install latest video card drivers, and try (by the way, can you tell us your system characteristics?) Try also put down texture resolution in rendering. Start with the lowest (I know it is very uggly but if the textures are loaded, then means it is because VRAM). we have to go step by step to find your problem. cheers,
