[fixed] Models from .obj files don't show up anymore

[mik_igra]

Hi, i worked with Wings3d like always but suddenly
models from .obj files don't show up anymore when imported. Just 1 hour before, i worked with wings3d and everything was fine.
Other models like .stl do show up and everything is ok. Only .obj files just don't show up , i reinstalled wings but its everywhere the same even in older version 1.5..

the .obj is loaded you can select something, but you don't see what you have selected, its blank, how could i make it visible again?

Welcome.

I assuming you were using the latest version.

Did you checked the console/log window to see if there's any message there?!

This "selective" behaviour is something strange to to happen. Difficult to evaluate since I have no problem with them.
The last one I opened was shared by another user in this post, in case you want to check it too: http://www.wings3d.com/forum/showthread....7#pid16437

when loading the .obj, in the log is written:
Ignoring: ["newmtl","houndhelm2"]
Ignoring: ["Ka","0.8","0.8","0.8"]
Ignoring: ["Kd","0.2","0.2","0.2"]



here is the same model as .stl it should look like this:

mik_igra, thanks for checking.

Those ignored "Ka" and "Kd" are no critical and should not represent the cause of the issue you are experiencing. (they should be related to the ignored material, since they represents the ambient and diffuse colour of a material). By ignoring it the 'default' material is used as replacement.

the .obj is loaded you can select something, but you don't see what you have selected, its blank, how could i make it visible again?

I read better this sentence and I have to ask you: Since you says it loads and some selection seem do be done, did you try, in Body selection mode, use the command "Invert" and see if something changes for you?

In which application these .obj files were generated? Any chance it has get an update and been exporting the .obj incorrectly?

If you load it in this online viewer (https://3dviewer.net/), did you see it correctly?

Also, could you share a screenshot of you geometry window.
It's very hard to try help without know what you are seeing once the issue is eventual and not reproducible on my side.

Here is what i see, on the number on top left you see that i have selected all faces.

There is no change with "Invert" function, still blank. The .obj files do work perfectly in every other 3d program, if its 3d craft, dead deer, meshmixer, blender...(but they all have an awful slow workprogress) just as it worked in Wings3d only 1 hour before... it did not work anymore.
Its ridiculous, Wings is the only program affected while it's the only one i am using.

Also there is everything fine with the exporting program, it must have something to do with my computer, so are there additional files Wings3d is needing? redistribution C+++... DirectX?

For example one time, one of these framework files suddenly didn't work properly and because of that one program wasn't running anymore, so i reinstalled the framework pack and it was working again.

You just remembered my brother. He also starts sentence like this.

I saw the image and it says me that your model was loaded.
Now, what I can think about is related to scale (it's size). It can be imported so tiny that it's a "dot" on screen or bigger that the camera is "inside of it".

You can check this theory by using the frame command.
Be sure to get everything selected by using Select->All [CTRL]+[A] and then View->Frame Selected [SHIFT]+[A]. (I'm in doubt about the shortcut, so check them via main menu - top one)

If you see your model, take a look at the bottom-right corner in geometry window to see the scale at that moment.

By being scaling your model in the importer dialog would explain this behaviour happening only for .obj file and not other formats.
You can check in the importer if that scale is different of 1 which is the default.


And yeah, Wings3D uses Vcredist, which you can replace/update it by reinstalling Wings3D and in the dialog you mark the box related to Microsoft... that should be uncheck at this moment since you already have it installed.

import scale? 0 ... oops, how this happened.

I usually drag and drop it in so i don't see this menu.
Thank you so much for your help :-), i was already about to backup my files and reinstall the whole OS, guess you can close this now.

Yeah, how that happened.
Thanks for the feedback.

Happy Holidays!
