thank you a lot!
i tried again with weight painting and adding topology but i still encountered the same errors.
but then i read again and thought about what you said on vertex weights and something clicked.
i added some extra loops around the areas and i then decided to try to determine instead which vertices i didn’t want to affect the mesh (i always thought the opposite, how to paint/add to correct the weights with draw/add/subtract and i always end up to mess with the automatic weights).
so i started painting with the draw brush with weight set to 0.0 / strength set to 1.0 and i removed the vertices i didn’t want to affect the mesh/bones and i finally achieved a quite good smooth result.
i’ll continue to work on it as soon as i find some free time and post some screenshots
thanks again 🙂
