How do I set up the path to mmgtools on Windows?

[tin2tin]

There is a Windows build here of mmgtools: https://forum.mmgtools.org/t/windows-compilation-succed-with-visualstudio/184/11

How do I set up the path to mmgtools in your Blender add-on?

[tin2tin]

Tried this in fn_soft.py, but it didn't work:

mmgsExe = "mmgs_O3 " if (platform.system() == "Linux" or platform.system() == "Darwin") else None

if platform.system() == "Windows":
    convertExe = "magick.exe convert "
    montageExe = "magick.exe montage "
    composeExe = "magick.exe composite "
    mmgsExe = "C:\\Users\\User\\Downloads\\bin\\bin\\mmgs_O3.exe "

Short: I have close to no idea, just specifying the path should have worked. Longer: I'll try to have a look in the coming days as I don't have much time right now. If I manage to make it work correctly, I guess that I'll "externalize" the mmgs add-on, which could benefit from an add-on by itself. Thanks for your interests, let me know if you find other stuff not working (which most probably will be the case, especially around the material imports and baking operations!)

The Windows mmgtools are now available on the mmgtools download page: http://www.mmgtools.org/mmg-remesher-downloads Maybe it is faster just to make the paths selectable in the UI of the add-on properties? (I'm not sure it works on Windows finding paths to installed apps in the registry? I have tried with other add-ons, but unsuccessfully )

Most options are greyed out. I get this error when hitting the MMGS button:

I wonder if the temp folder is missing or where it is generated, so I can check if it is existing?

Hi again. I had a quick look, and indeed managed to make mmgs work on Windows. Your suggestion to make the executable paths selectable in the user preferences is indeed the good one and I'll modify the add-on tonight/this weekend as I'm short on time right now. The error message seems to be caused by blender trying to write tmp.mesh in the folder where it is executed (which is protected on Windows, but should work if you launch blender or blender.exe from the Powershell). For a quick fix, you could try replacing "tmp.mesh" with something such as "C:\Users\User\Desktop" for instance. I'll adress this soon. Cheers!

Hi again! Concerning the error message you got on windows, it is due to the fact that mmgs does not output an error code of 0 on successfull completion. Could you try installing this .zip addon, which comes from the "dev" branch, and telling me if the fix works for you? (No need to modify the "advanced" options in the mmgs modal.). Thanks!

[tin2tin]

Wow, so much you have done with the UI. It's really super cool.

Unfortunately all four remeshers are giving me errors: [image: image.png]

Btw. in the preferences there are no options to add paths to the executive files? Is this the reason to those errors?

OK, the zipping method I used was not the good one, and having a file called BakeMyScan-dev.zip instead of BakeMyScan.zip does not go well with the user preferences... That was most probably the reason to the errors (although I did not see the picture you attached). I hope that finally this .zip should work for you! (it worked for me between linux and windows).

[tin2tin]

Yes, the executive files now works(on Windows)!! :-) Looking forward to test all the rest of the functions, if that's okay with you?

[norgeotloic]

Yay!! Of course, I am more than OK with you testing the rest of the add-on, you are actually keeping me motivated to properly polish it :) May I advice you to wait a few days though? The baking part still needs lots improvement to be transparent to use... I'm closing this issue, but do not hesitate to open another one or to add a comment on the "TODO list" if you see anything which might be important in the meanwhile... Thanks for your patience :)!
