In Vavoom 1.22 (both Windows and Linux Version), if MD2 models are used, the texture models of Chaingun and Chainsaw Doom weapons are not loaded. Debug says:

(for chainsaw)
Log: Couldn't create texture models/weapons/v_saw.pcx.
repeatly....

(for chaingun)
Log: Couldn't create texture models/weapons/v_chain.pcx.
repeatly....

Version 1.21.2 with the same models works fine.

Haven't tested this myself, but I think it's fixed in the latest SVN patches.

I've tried now with the latest SVN source code, but the problem still persist! <!-- s:cry: --><img src="{SMILIES_PATH}/icon_cry.gif" alt=":cry:" title="Crying or Very sad" /><!-- s:cry: -->

There were problems with some of the skins. I uploaded an updated model pack.
