Very impressive, I thought for a moment that it was a real photograph.

By the way, here is another very detailed one:
http://www.blendswap.com/blends/view/71861
The untextured mesh is free, so it might be interesting to play with it.
You need to register there, but it's OK. I registered a few months ago, and they didn't bother me with ads or stuff.

It's a Blender file. I opened it in Blender, and tried to export it. Unfortunately the main truss doesn't export, no matter what I do. I selected all parts including the truss, but when I open the exported OBJ or even 3ds, the truss is missing. Any Blender specialists out there?

Hannes, pretty sure I'm not what you would call a "specialist" but I'll download it in a bit and see if I can figure out what the problem is.

Make sure it is a mesh and not a curve that has not been converted to mesh also. (By no means a specialist either)

Thanks in advance!
I also opened the object in PoseRay. The truss is missing, but the rest looks good. But there's an issue with normals after you reimport the mesh into other apps, even after recalculating them.
In 3dsMax there are some flipped normals. In TG it looks good at first sight, but if you look closer you can see, that there's something wrong with them. Even with the same shader they look different somehow.
I read, that this occurs quite often, when you export meshes from Blender.  :(

Can you identify the mesh as a single mesh, or is it about 50 in a group to make the truss? You might try selecting and make a new group then join to whole again...

If you can identify it as one mesh, could you, in a new file, append that mesh and then export as a new object, just the truss?

There are all sorts of professional methods which I do not know, but I too cannot get an arch to stay attached to my hotel object....it is a simple mesh but made in a quick easy method that obviously does not export well. I am sure it is my method of joining it, as it will export as a separate mesh just fine.

I am sure you already tried all this simple stuff.

Actually I feel a bit lost in Blender. I only installed it to convert Blender objects. Otherwise I have absolutely no experience with this program. I'm sure it's fantastic, but not very intuitive.
Thanks for your tips! I'll try to find out how to do what you mentioned.

ok, I've attached two renders of the  ISS, with no modifications made to the Blend file.
Hans, can you please reference the ISS1-Blender file below and tell me what's missing?
I've circled what I "think" is the section you referenced.
Thanks.

Yes, that's exactly the part that's missing!

ok, could you re-download the blend file  from the link you provided, export as OBJ and try to render in T4 again?
I didn't make any changes but it rendered ok for me in the second image. Might have been noticed and fixed recently.
If that doesn't work I'll send you the OBJ file I just created and you can see if that renders correctly on your machine.

I dl'd the fbx and fbm files and am going to try them in DAZ which has handled all my fbx files so far. When my current render finishes that is.
something borrowed,
something Blue.

Thanks again, Masonspappy!!! I gave it another try, and found what was going on. The first time after I had exported the .obj I opened it in PoseRay and got some sort of a giant bathtub, which looked weird, so I converted it to .3ds and then back to .obj, and in the end the truss was missing.
So I exported the file again from Blender as .obj, opened it in PoseRay again, and took a closer look. See attached image, what I got. When I imported it into TG, the structure was there too.
OK, now I saw, that everything was there, including the truss, and the extraordinary orbital bathtub. I could easily delete this part in 3ds Max. Still no idea what this is. I hope, that it's no blown up representation of some crucial part, that's now missing, but it looks OK so far.

In some areas this mesh is more detailed than the NASA one, but there are other parts, where NASA is winning. It's probably way more complicated to texture this one, since there is NOTHING set so far, but maybe I'll give it a go.
