For some reason, this Mesh won't let itself be weight painted. No matter what I do, I can't really paint more weights on it, specially not in face mask mode which I kinda need.

Does anybody know why?

I see two reasons:

  • Mode is face selection masking: so you need to select faces (A or right click select)

  • The setting is to subtract and there is no weight to subtract

  • $\begingroup$ Sweet! Do you have any idea why it won't paint when the "limit selection to visible" setting is switched? $\endgroup$

  • $\begingroup$ Yes, because some normals are inverted (back facing) $\endgroup$

  • $\begingroup$ I see, do you know how I could invert them? $\endgroup$

  • $\begingroup$ To do it easily... no. Doing it face per face... : (. This often occurs with garments (because what is front becomes back when you fold it) and this is not so easy to handle. $\endgroup$
