Bone Heat Weighting: failed to find solution for one or more bones error

hi huys i make this model but i get this error I think I tried everything but I couldn’t solve the problem can you help me?

its blender file link :

hello, your link asks for an authorization, we can’t download :wink:

sorry , i fixed it

It’s now accessible but I can’t see any download link :confused:

i fixed it again sorry

In Edit mode select all and press Shift N to recalculate the normals, and you must have overlapping vertices so press M to Merge by Distance. Also I’m not sure it’s a good idea to give thickness to your mesh

I’m sorry, I don’t quite understand, can you do it and send the file to me?

sure, here it is:


bro thank you soooo much , I’ve been trying to fix it since yesterday :heart_eyes:
