[Solved] Model issues

[Acies]

Hi!
There are some issues with weight painting my mesh. Whenever I do it the mesh becomes "destroyed" - looks like the model has swallowed a grenade.

How should one go about correcting the weights on a model?

Problem 1 (solved):
I have been trying to texture a tree. In maya everything looks fine. I have one texture for the leaves and one texture for the stem of the tree. I have tried to follow the: http://wiki.frictionalgames.com/hpl2/tut...loutsource
for creating objects with several parts/textures.

It comes out like this (no leaves on it):

Any suggestions for me?

-- Noticed another error --
Several entries of (in modelview.log):
ERROR: Bad normal 70504 in mesh C:/Program/Amnesia - The Dark Descent/redist/models/data/viewer/pinktree/pinktree.dae! Length is not 1. Will not cache file!

Problem 2:
Another model (one of the amnesia justine models) is duplicated when I export it. Both skeleton and mesh. All I have done is to add a very simple skeleton.

One of Hermoor's models (the girl) has the same issue. When I export it the model recieves two extra "skeleton arms".

I would be very happy if someone could help me with issue 1 or 2
