There seems to be no misalignments with all the limbs.

The fist is parented to forearm (forearm has a sibling also called shoulder/upperarm), which is parented to a different shoulder, which is parented to the vanilla limb.

There seems to be a invisible patch on all of my arms.

IN ADDITION: I have tried to export the 128x128 skin with a gist, but no "Successfully exported X" message, and the export seems to not happen. So my character works but cannot be exported for some reason.

EDIT: IDK if the main bug existed in prior versions.

Please post your project file. (You have to zip it to upload it to github).

Here it is.
MothDude.cpmproject.zip

Your texture is built for 6x8x6 part and you are only using 5x8x5 part, thats why it shows up weirdly in game. In the editor your part has a size of 5.000001 (somehow?) for the width and depth which maps a 6x8x6 texture instead the 5x8x5. Go over your parts and type in 5 into the text box to set them to the correct value.

I also tested the export and it worked fine for me. Please post your minecraft log.

Sorry for the messy paste, minecraft logs don't seem to save as files without copy/pasting them. This is an excerpt pulled from the STDOUT AND STDERR blocks of the log. If you want the whole log, let me know.

BIG EDIT: I found the log file and posted it in a later comment! Sorry for wasting your time.

-IGNORE THIS PASTE (ONLY HERE SINCE IT WAS FIRST, AND DELETING IT WOULD BE AWKWARD) UNLESS ABSOLUTELY NECESSARY-

Also in my version, I no longer seem able to right click for move/place or duplicate anymore.

EDIT: This specific bug disappeared after rebooting minecraft, so move/place and duplicate works again.

Oh I actually finally figured out where the logs are stored... I guess the tutorial I watched taught me wrong.

Here is the full log:

2021-04-12-2.log

Please try the new version 0.0.12a

Ok, so problem have been fixed, thanks to your new warning about vanilla being 64x64 only.

I did not understand prior to 12a why it didn't work.

After 12a, I did more research and figured out the intention of the vanilla skin (although it should have been obvious, I didn't think that clearly)

I now consider vanilla skin separate from the modded skin, and the issue has been resolved.

I can now begin to work on the project once more! Thank you for at least adding that warning as a result of #63.
