Cannot save textures

I’m trying to save the textures (from Rhino render) of a model but for some reason only 1 texture is saved when I reopen the file. Does anyone know why? Thanks.

I’m guessing this is with Windows Rhino 5 SR12 but say otherwise of that’s the case. Are you using the save textures check box in the Save As dialog or the check box to Embed support files in Options>Document Properties>Rendering? I’d try the latter and then save again with that setting enabled. The command line will report the embedding of each texture map.
