I am modelling some simple buildings in Blender and importing them to Poser 8 as obj files. I wanted to apply some image map textures to them in the material room,  but I am getting really bad results when rendering.

I then tried it out on the primitive square.

Here is a screen capture of the preview of the square with the texture applied.

Here is what I get when I render it with Firefly.

I tried the same thing in Poser Pro. I also get black marks when rendering with Firefly in Poser Pro, but with the Poser 4 renderer it renders fine.

I updated my video card driver, no effect. I am using an NVidia GeForce 9500 GT with 2 GB of Video Ram. Quadcore machine running Vista Business 32 Bit, 4GB of RAM installed.

Everything else renders without any problem. I seem to get this with flat surfaces with image map textures applied, where the object is not UV-Mapped.

Is this a known problem that I am just encountering now?
