Please I need some help. I've just finished modelling a house using BLENDER. After adding textures, I exported the mesh as a wavefront(.obj) file into POSER to use with their human figures. But unfortunately, when the file was eventually imported into POSER, most of the textures that I had pain stakingly applied in BLENDER, including glass textures and many image textures for the rug, roof etc did not load in the mesh. Please can anyone who knows how to use both softwares help me with anything that I can use to rectify this problem. I have attached pictures of both the renders I did with both softwares. The rendered image using POSER is a far cry from that of BLENDER.

You have to painstakingly reapply them in Poser. :O)

personally I prefer to import figures from poser into blender......

I've imported a fair-few objects from Blender into Poser. You might want to save out your obj as a pp2 or cr2, save all your textures in your folder under runtime:textures and then open either the pp2 or cr2 in NotePad++ or something of that quality and check the paths. The materials will be there: all you might have to do is fix the paths.

However, that's only a small part of getting good renders in Poser, the bigger part of which is sorting out your materials in the material room (ie, nodes).

you can have the export include materials if you actually mean textures.  it will generate an mtl file, but since textures are only a small part of my materials, i've never bothered to try to get Poser to understand that mtl file.  but you mention glass, and since i see only two or three actual textures in your Blender render, i'm betting you mean materials instead of textures.  glass, for instance, is generally a defined material, not a texture, which is just the bitmap you're applying to the diffuse color.  materials are application, or renderer, specific.  you have to set them up in your rendering application.  if you weren't going to render in Blender, setting up materials there didn't do much for you.  i'm pretty sure Blender's internal renderer has lots of power Poser's Firefly does not, but that Firefly can't do anything Blender's can't.  i still use Poser for rendering because i loathe Blender's camera management, and SSS and a little more power with lights doesn't make up for the fact that i know how to create good materials and light with Poser.  if your scene, materials and lighting in Blender is already further along than in Poser, you might as well bring your figures into Blender and render from there.  especially since Blender's renderer is developing fast enough that what it can't do now, it will probably do in the next year or so. Firefly hasn't adopted new features so quickly.
