butter, Ya know I misread your problem - sorry about that. generally P5 doesn't use .bum files and for the most part P5 artists have quit including them with their meshes. bum was a red/green based .bmp file renamed .bum for use in P4. You will probably have to convert the bumpmap texture to a .bum (.bmp) somehow. I haven't kept up with how to go about doing that but you would probably have some luck asking in Poser Forum or you could ask the artist if they could create a bum file. It might not work to use a .bum with a P5 mesh but Ockham, Geep or Nerd (to name a few) on Poser Forum would know that for sure. - TJ
