OK, I've now tested with Apollo as well, and got the same result, i.e. put the geometries and textures in Apollo's runtime. But, when I went to load up Apollo it went searching in the main runtime.

So...this being the case, why is it preferable to put the geometries and textures in the same runtime.

The only other thing that I can think of is that I am not using the Poser library palette, rather I am using the P3DO Explorer to load up content. Wonder if that is making a difference ?
