Here's another editing tip for you...!
I decided that I'd have a go at creating my own texture
(*.MAT) file to personalise my level. I had some trouble
with this, but here's the EASY way of doing it yourself.

1. Decide which MAT you want to customise - I found it
easier to use the texture selector in JED and pick which
one I wanted, noting the name down as well as the
ColourMap (.CMP) it uses.

2. Use ConMan or a similar extractor program to extract
the .MAT and .CMP files you need from the JKRES.GOO file.

3. Use MatMaster or a similar MAT extraction program to
decode the .MAT file out you selected. This will extract
it to one or more .BMP files

4. Use your favourite Graphics program to make a copy
and edit the .BMP file. I used Adobe PhotoShop as it
smooths out and blends superbly. The only problem is
that PhotoShop likes 16mil colours- MatMaster doesn't!

4b I then used Paint Shop Pro to load in the *original*
.BMP I extracted from the .MAT file. I then used the
Palette options to save out the palette of the original.
I then Loaded my custom .BMP and then loaded in the saved
Palette. This instantly restored the palette to the original!
This got round all the problems I had with my Paint programs
screwing the colours up when picking my custom .MATs
from the Texture picker in JED.

5. Save, GOB and run your level!
