[patched] (2.2.7) Wings 3D crash when import obj. in Win 10

[olve11]

Hy there,

I need to report a crash of Wings 3D 2.2.7
I used OS Win 10 64 bit

built Windows 10 Home 20H2

My spec.
AMD Ryzen 5 1600 Six-Core Processor 3.20 GHz
8,00 GB DDR4
AMD R7 370 2GB
motherboard - GIGABYTE B450M DS3H V2

When I import the model in .obj format to Wings - crashed down
no crash report generated

import setup:
Swap Y and Z Axes


Thanks

Is this file available for download somewhere?

I'm asking because the .obj files I have (even some problematics ones that someone shared with me) are still loading without any problem.
It should be something in this file.

Hi micheus,

In Wings version 2.2.6.1 I have no problem with this

[micheus]

No problem here...


Just in case, here is it in wings format.

I've just downloaded 2.2.7 and am having the same crash. Based on a message in the log about textures I've done a quick test :
To test, in another program I've created a single cube and saved as an obj. This opens fine in 2.2.7. I then applied an image texture to the cube and saved again. This one crashes. The log is below.

To test,
1) in another program I've created a single cube and saved as an obj.
2) This opens fine in 2.2.7.
3) I then applied an image texture to the cube and saved again. This one crashes.

Please, can you detail the step 3:
- Was the .obj UV mapped in the other app?
- if not, was UV mapped in Wings3D before you assign the image?
- How did you assigned the image? you have loaded from HD or created it in Wings3D just for test(like one of those patterns, checkers, horiz line, vert line);
- Does the object has any material assigned to it or were you using the default one and attached the image to its Base Color property?

Sorry, but I need these information in order to try replicate the issue, because I couldn't.

Eventually, you can share this problematic file (as a .wings files) and then I try to export it here and see if I can get the issie.

[noisybirds]

Hi @micheus,
I didn't explicitly UV map the cube in the .obj file - all I did was change the default material to use the image as the base colour. It was created in the other program, Wings was only used when I tried to import it. I only have the .obj file as a result.

obj
https://drive.google.com/file/d/1Rompxed...sp=sharing
mtl file
https://drive.google.com/file/d/1BjQCV25...sp=sharing

---

Okay, I have reproduced it in wings.
Create a texture externally (256x256 png)
Create a standard cube.
Import the image
Assign the image to the default material. Cube now has the texture.
Save as obj
File new
File import

Thanks for a more detailed steps.
I repeat them and I couldn't get the crash. Which would be strange, if I haven't remembered I made a path for it.

Sorry for not remember before. Please check the Patches/Fixes for Wings3D and apply the ones for your version.

[noisybirds]

I applied the tar and beam file for 2.2.7 and I'm not seeing any crashes with the files I was having crashes with earlier. Thanks for the help @micheus!

[micheus]

Nice. Thanks for the feedback.
