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.

This stands true for most 3d rendering programs - textures meed to be defined and applied in the program you will use for rendering. Even in high end applications, texture definitions don't transfer very well.  Poser only reads it's own texture definitions, and doesn't import them from other apps (at least not very well).  Only imports the mesh geometry.

Did Blender export a .mtl file with your .obj?  If not, Poser won't look for any textures upon import.  Are the textures you're using in Blender packed?  If they are, they'll need to be unpacked for Poser to find them.  (Umm.  I should probably ask, too, if you'd exported from Blender using .obj....)

I recently exported a .obj from Blender and had to unpack all of the textures, then place them with the .obj and .mtl in the same folder.  Then Poser imported everything correctly.

You will lose any texturing which is applied on the shader level when doing I/O between Blender and Poser, unfortunately.  Only a texture map and the diffuse, specular, ambient, (and possibly transparency?) settings will be passed by the .mtl.

so far, what i've done is create a separate folder to go in Textures, with the actual jpgs that were used in the modeling program (Wings 3d). Seems to work ok. Only thing that ever gets me is scaling to and from Poser...;)
