      Thanks, its just a test anyway.
      SU model exported via SUpro obj exporter (collada blender importer leads to a complete useless mess). I had first to 'explode' components and turn them to groups. I had to check that faces look outside (white color, not blue). After imported to blender, had to select all vertices and remove some doubles. Triangles to quads (this makes UV unwrap and displacements simpler). All these were one click operations. Now I was ready to texture and render in blender. Some more tips. When building windows in SU, its better to avoid all this push-pull, just do the openings and keep the rest stuff as a separate group, makes texturing easier, produces better topology too.
      To render in blender means a lot of clicks, lots of material properties, lot of experimentation. What do you expect? Its an advanced renderer. (more than kerkythea). If asking for a friendlier renderer then... well, podium is my favorite. πŸ˜„

        I'm surprised that's not their slogan.
        Podium - The Friendlier Renderer.

        Seriously, thank you Michalis for your contributions and ideas. I have 3ds Max and Modo, but have been slowly exploring Blender. I'd love to get away from the upgrade money pit that is most paid apps these days.

          Haha....The Friendlier Renderer....we might adopt it.

          It seems I will have to start exploring this Blender as well.

            rendered in blender v2.5 internal renderer (~1 min).

            lovely! beautiful light and shadow!

            michaliszissiou, what resolution was this rendering? what machine/processors/processor speed?

              Thanks Adam, Sid, Fletch. Rendered at 1680x1060, blender v2.5 64bit on a mac (two xeon-nehalem, quad cores 16 threads at 2.26 Ghz). But could take 5 or 10 or 20 min, so many variations. I could say that ~1min on v2.5 or ~5min on v2.49b. What made this fast is that avoided radiosity solution using just a sun and three emitters. Blender aims at animation, so its fast.

                Cool quiet images β˜€

                The collada exporter from SU free seems don't work with the Blender Collada Importer
                But seems work when you export from SU free in KMZ (rename in .Zip, unzip = DAE) then import in Blender πŸ˜‰

                  Thanks Pilou, but DAE in KMZ is identical to DAE export. A mess. Practically useless!! Its collada blender importer or a SU problem, or I'm doing something wrong. πŸ˜†

                    Probably both, but it's the only thing that I can do now from the free Su for export an object directly inside the Blender 2.5 Alpha 0 πŸ˜‰

                      I'll second that SU DAE to Blender Collada import stinks, I exported a building and it's gigantic mess of triangulated faces and half reversed normals. On any serious model you'll spend longer fixing normals and cleaning up faces than you ever did modeling it.

                        Exactly so. Maybe we should forget texturing in SU. Anyway UV texturing is superb in blender. Maybe this 'importing SU models to blender' operation is a waste of time. Maybe... πŸ˜’

                          Hi,
                          It's nice to see another user of a SU/Blender workflow. I love the two programs and they make my life more easy.
                          SU is great for modeling architecture but Blender as more advance tools for modeling organic forms,texturing and render.
                          My workflow is:
                          I use SU free for modeling from the CAD files and do texturing, then use the Kerkythea exporter, then I have a Kerkythea XML file and the textures folder.
                          Then use the wonderful Nicetuna converter from the Kerkythea format into OBJ, it can be found here: http://www.nicetuna.com/kt2obj
                          Then import into Blender the OBJ file,be sure that the file are in the same folder that the textures and in the import options check the image search for Blender find them, and separate OBJ by Object/Group/Material. And VoilΓ‘.
                          The import is perfect.
                          In Blender you just need to delete duplicate vertices and transform tri faces into quads,that are very simple commands.

                          Then one can export back to Kerky for render or use another render engine available for Blender like Yafaray, Luxrender or VRay.
                          This is how I do it. Hope someone finds this information useful.

                            Thanks Camara. Interesting workflow. I am going to give that a shot.

                            EDIT - Gave it a shot and it works great in 2.49. I can't seem to import .obj into 2.5 alpha. Anyone else have this problem? BTW - the KT .xml to .obl workflow also works great for going from SU to Modo.

                                  OK, blender 2.5 is Alpha 0, lets work with v2.49b. Lets keep v2.5 for rendering.
                                  Its a small tutorial here. Exporting from SUpro as .obj. Exporting textures too. When impoted to blender check for doubles. I didn't find any though. If models are already textured in SU, DO NOT convert triangles to quads, UV problem. You can edit UV textures however, you can even have texture painting, projected textures etc. Everything works just fine, just don't subdivide geometry (bad triangulated SU models here).
                                  Here's an old SU model:
                                  SU.jpg

                                  As you may noticed I'm checking faces so to look outside, that's really important. No blue faces, ok
                                  Picture 1.jpg

                                  So in SUpro, export .obj like this:
                                  Picture 2.jpg

                                  Importing .obj in blender 2.49b like this.
                                  Picture 3.jpg

                                  Here's the model in blender. You can see on the right, all textures UVs etc have imported beautifully.
                                  I deleted cactus and added some blender trees BTW. Everything works like a charm
                                  Picture 4.jpg

                                  A quick render ~2 min
                                  mmm.jpg

                                          Michalis, does this mean that you will import into 2.49 first, then save as .blend file and open it in 2.5 for rendering? Just trying to understand the workflow. I can't wait until they are finished with 2.5. It is a real gem in the making...especially if it is still free!!

                                          Also where do you get your Blender trees?

                                            Yes Adam. You can save the v2.49b file and open it in 2.5 (much faster renderer). But you have to wait for a full functional 2.5.
                                            As for "if it is still free" read this one. It will always be a freeware app.
