[fixed] No-extension filename failed to cooperation with renderer.

[tkbd]

In the state of unsaved Wings data, export file name is blank.
If a file name is blank,an user may save the file without the extension.
Especially such file makes fail to cooperation between a renderer and Wings3D.

An error recreate procedure(For example,use Yafaray exporter).

1. File>New.. make some 3D object (It does not save.)
2. File＞Render>Yafaray... Click OK button in setting dialog
3. Next,File Dialog is appear but filename box is blank.
4. so input "render_test" in filename text box, and do rendering.
   

Result:

• Rendering is success,then "render_test.tga" is saved.
• But Wings3D indicated an error message window 'No Image rendered'.
• Also, an item of "<<rendered>>" (Image data) doesn't add to outliner.
  

(It was tried with Wings3D 2.0.1 on OSX)

Suggestion:
I think that necessary to devise for the user does not make mistakes.
For example,when unsaved state, to autofill the filename "Untitled" and extensions in export dialog.
Untitled.tga
Untitled.bmp
Untitled.svg
etc...

tkbd,
Usually when one gets a "No image rendered" message it is because no image is rendered. This can happen with Photon Mapping and/or Pathtracing, if not enough photons are present. You will usually see a message similar to the following in the Log window when that happens. The solution is to add more lights to the scene...

INFO: PhotonMap: Building diffuse photon map...

INFO: [ ] (0%)ERROR: PhotonMap: lightPDF sample error! 0/0... stopping now.


It is strange that you are getting a successful render when this happens. Maybe it is different with OSX.

I do not know if Wings3D can be changed to add the actual rendered name instead of <<rendered>> to the Outliner. This is how it works for Kerkythea and Pov-Ray as well. I may have requested this in the past, if I remember right. I think the response was that the Wings file is not intended to be a container for rendered images. I will usually rename <,rendered>. to a new name in the Outliner if I get a good render and then make it internal for safe keeping.

We will have to see what dgud and/or micheus have to say...

I fixed it to work that way.
