Applying different texture to b3d file

Hi all,

I have a quick question that I hope somebody could shed some light on. I have a b3d file, exported via b3d pipeline from max, and a texture. I load the mesh in Blitz, and it displays fine and with texture. Problem is, when I then load a different texture and try to apply it to the model using the EntityTexture command, nothing happens. Any idea why this might be happening - is there a particular setting in b3d pipeline to watch out for?

Thanks in advance for any help.
