WATER for GlQuake 1.02 Readme
(c) 1997 by Baby Joe

WHAT DOES WATER DO?
===================
WATER modifies Quake level maps (BSPs) so that water, slime or even
lava surfaces becomes translucent. AND: Now you can see ITEMS and
MONSTERS (Deathmatchplayers) through the surface!
It is not an enhanced VIS program and it can't replace VIS, but it
modifies the BSP's Vis-Data using some simple rules:

-	Water areas (leaves) are marked as always visible
	for the case you're outside water,

-	optionally all non-water leaves are marked as visible
	for the case you're inside water leaves. This option slows
	down things quite a lot, but only if you're submerged.

WATER only needs the BSP file, no PRT or whatsoever data needed.
This has the advantage that it can modify the original Quake-maps,
eg DM3 (which runs well).
Disadvantage:
Speed loss. Depending on how much water there is in a level, speed
can go down.
And... Also Monsters seem to profit from the modifications, they too
can now see through water. Hm.

WHAT'S NEW / BUGFIXES
=====================
1.02 (04/04/97) 2nd try

-	Found a bug with the '-x' option: Under certain circumstances
	it would slow down things even outside water, which is unnecessary.
	I claimed it wouldn't... ehem. Well there's got to be reason for
	updates! ;-)

1.01 (04/04/97)

-	Played around with the magic formula... and: Works much better
	now. Modified BSPs should run a bit faster now and underwater
	things should look much better in formerly buggy levels.
-	command line parsing should be ok now


WHAT'S IN THIS PACKAGE
======================

WATER102.TXT
WATER.EXE	The main exe
CONVERT.BAT	Converts single extracted BSPs, keeping the original name
CONVERT!.BAT	Converts a selection of Quake-maps, which have to be
                already extracted (eg use UNPACK.BAT)
UNPACK.BAT      Unpacks the files pak0.pak and pak1.pak using
SWUNPACK.EXE    This util isn't made by me. I hope the author doesn't mind
                that i included it in this package.
QCLEAN.BAT	Deletes files created by UNPACK.BAT and CONVERT!.BAT
		ATTENTION! May also delete other 3rd party files!

WHAT YOU SHOULD KNOW
====================

If you just call WATER.EXE without switches it will try to explain itself.
CONVERT.BAT backs up the original BSP file (extension .BAK).
CONVERT!.BAT uses CONVERT.BAT, so after using CONVERT!.BAT there are
some BAKs which can be deleted.
BUT: Keep your pak0.bak and pak1.bak! Then you'll be able to restore
the original state by renaming them to pak0.pak and pak1.pak.

If you want to see a really great level, convert DM3 and enjoy!

WATER has been tested with GlQuake v0.93 only (Monster 3D).

Always remember: R_WATERALPHA 0.3! No longer needed is R_NOVIS 1.

If you don't use the extra lava option, lava appears some sort of
blurry. This isn't my fault: GlQuake makes no difference between
lava and water translucency.

WATER.EXE checks itself for changes. If it finds out a change
(maybe a virus infection) it will reject to run. This could also be
the case if you use virus protection programs which save information
at the end of .EXE files.

Please check both .EXEs for viruses! Although you can be shure that
I don't WANT to infect your machine, i can't guarantee that my one is
clean.

WHERE YOU SHOULD PUT THESE FILES
================================

WATER.EXE       QUAKE\ID1\MAPS or somewhere in your PATH
                         If ^ doesn't exist, create it.
CONVERT.BAT     QUAKE\ID1\MAPS
CONVERT!.BAT    QUAKE\ID1\MAPS

SWUNPACK.EXE    QUAKE\ID1
UNPACK.BAT      QUAKE\ID1

KNOWN BUGS
==========

I've tested all original Quake-maps, here are the results:

Graphic failures
----------------
In v1.00 there were a lot of bugs. Most of them have vanished now,
but there may be still some which i didn't discover.
(I don't want to check all the levels over and over again...)

The following levels are excluded from conversion by default:
(because they are too slow or because they don't contain water)
 - look at convert!.bat
---------------------------------------------------------------

S : too slow
L : only lava
N : no water (of importance)

E1M6 L
E1M7 L
E1M8 L
E3M2 L
