I wanted to share a modification I made to make Simply Hammer support texturing better.
Those changed files make:

1. handhold Simply hammers support semi-Transparent textures:
   HammerSimplyRender.java
2. all model parts with different dimensions have a different texture:
   SimplyHammer.java

I made an ImageMagic auto-convert script (old texture files=>new texture files) for linux, should be easily transferable to work with Windows.
autoconvert.sh

usage:
$ cd /path/to/autoconvert.sh/
$ ./autoconvert.sh Source Destination

I converted all model textures that come with Simply Hammer and created a semi-transparent glass-like model texture for the Unstable hammer.
orginal-converted.zip

Use everything if you like, in every way you like.

PERFECT UNSTABLE HAMMER TEXTURE :))))

Ooo... Big Thanks.
