Python windows has just one function to get a render-size. This function delivers no correct values if the renderwindow is docked. You have to set the size under Menu->Render->Render Dimension.

That one works pretty well on the exporter's side; It's just tedious on the Poser side, as we all are used to have preview = render size. I guess it will get easier when the GUI reminds you about the render size.

The problem is with the camera setting. Check my renders further up. I used v.10e, straight (no GUI), and expected to find the same focal length (around 100mm, IIRC); Apparently it differed a little. Now I don't know if it is because 100mm in Poser and 100mm in Lux mean different things (most likely), or if there was an export hiccup. Sorry, exporter files being always overwritten, i don't have them anymore, and I didn't think to check at that moment.

Note, the current version now is v0.11.1.  adp had posted that he accidentally included the wrong camera exporter, and the new version has the correct one.
