[Fixed] Blender 4.2 - 4.3 | Applink not working

[daglask]

Hi all newbie here to 3dcoat

I have blender 4.3 portable . So the  python popo-up menu warning about  data.json not found was logical. All my config and extensions are in portable folder.

What i did is this workaround . I created a symbolic link to where the program wanted the data.json file to be. ie C:\Users\admin\AppData\Roaming\Blender Foundation\Blender\4.3\extensions\blender_org\coat_applink\data.json. Of course i didn't make the symbolic link only for the data.json file but the whole folder

coat_applink .  I tested a couple of times and is working .  

On the other hand i may test only silly things ..

Please let me know

I tested v.30 and Blender 4.3.0 and found it working as expected

My version (attached) is located into

C:\Users\<username>\AppData\Roaming\Blender Foundation\Blender\4.3\extensions\user_default\io_coat3D

any reference on scripts/addons folder was deleted

io_coat3D.rar 92.39 kB · 1 download

Ok . Dont let Blender copy Config files from previous Blender. It appears to corrupts the 3dcoat app at least for me. Fresh install and everything works.

I'm pretty sure applink has a recent bug in the code. It's doubling some of the \'s. I'm getting errors like this when I try to export:
 

RuntimeError: Error: Python: Traceback (most recent call last):

I do have a 3DC2Blender file in my Documents folder. The only thing I can see it not being able to find it is because of the \\'s

Im Using Blender 4.3, 3dcoat 2024 30 and the 3dcoat app supplied by Carlos and the export works as expected. Do a fresh Blender install and dont allow Blender to copy Configuration from a previous Blender. For me this works.

When I made sure to download 4.3, I also noted not to copy configuration. So I set up all my configuration again. But to problem solve this, I went to Windows, Uninstalled 4.3, went to appdata\roaming, deleted 4.3 folder, and went to program files and deleted 4.3 folder from there too. I then reinstalled 4.3 from a hopefully clean start.

 

Still getting errors.

I guess that you need to setup the exchange folder

Unfortunately, that's set up too.

 

The only other issue I see is that I upgraded from Textura to 3DCoat. I uninstalled Textura, but maybe it's just stuck on that and I need to use a special uninstaller to remove everything from the registry and do re installation of Blender and 3DCoat? Would that make a difference?

[Carlosan]

applink only works on full version of 3DC, not for Textura

I took a fresh install of Blender 4.3, added the 3dcoat app and everything was automatically set up. FYI

Is there a step by step guide to load this app link on the Mac? I have the latest versions of both Blender and 3D COAT

Ok, so I figured part of the problem. Since my Documents are stored on a separate HDD, I had to create Applink files on the "other" Documents folder, that I do not have my PC default to. I am no longer getting errors, but I am not getting any option to place an object in my 3DCoat 2024 modeling mode, so I'm a bit stumped. (I am using 3DCoat. i UPGRADED from Textura) I've done all of the bottom after uninstalling Blender 4.3 again, and using an Uninstallr to clean up 3DCoat and reinstall it from scratch. I did NOT import any settings from older versions of Blender, and I deleted old 4.3 folders from appdata and Program Files to make sure no old residual settings remained.

What I've done (maybe I'm getting lost somewhere, there's things that have changed based on the guide):

1. Copied what is in \Program Files\3DCoat-2024\data\ToolsPresets\InstallAppLinks\Blender4x\files to \Program Files\Blender Foundation\Blender 4.3\4.3\scripts\addons_core\io_coat3D
2. Created User\AppLinks\3D-Coat\Exchange\, an import.txt, and a Blender folder in the folder
3. Created a User\3DC2Blender and an exchange_folder.txt that points to User\AppLinks\3D-Coat\Exchange.
4. Enabled 3D Coat in Blender, set exchange folder under Scene settings to User\AppLinks\3D-Coat\Exchange\ and saved new exchange folder.

 

Not sure what I'm missing here?

Sorry cant help you there. All of my programs are on the main drive, I only use the secondary for file storage.
