The specularity scale isn't set properly (should be better when it's like this: "setshaderparam specscale .7 .7 .7").
What about adding glowmaps at the light-textures? They aren't that great for using at the moment.
Also, put the folder in the "textures" folder instead. Sauerbraten already looks pretty messy because of all those individual folder with textures, skyboxes, models, sounds, etc just everywhere.
The digits should be flipped, they can't be used realistic now.

It's a really nice texture pack and I'm sure I'll use it if it has all of those "problems" are solved.

ok, i made some glow-textures for the lights and fixed the specscale, but why should i put the 2ond texture pack by philipk in the "textures" folder? he already has his own folder in "packages".. btw: the digits arent flipped ;) for example: make a wall and texture both sides with the same texture - one side is mirrored :P just use vflip ;)

There is no such command as "/vflip". It "could" be done with "/vrotate" and the values "4" or "5", but I noticed it's a pretty messy command which isn't that easy to use at all (like a command as "/vflip" would be).

ooops, i was sure there was sth like /vflip xD

Because mixing the two texture packs will cause confusion and will likely fuck things up. Placing everything in its own folder in "packages" might have been a trend when sauer was still young, but now things need to be organized. Period.

There are a lot of textures which don't need to be in the texture pack (like copies, original glowmaps, etc).

What about still renaming the textures so they all have lowercase? Use programs like Lupas Rename to rename files rapidly.
I'll do it this time, but I want to see it your doing next time.
Here's a link to it.

P.S.
I'm still waiting for the heightmaps :P!

OT: FreeCommander (http://www.freecommander.com/index.htm) also can rename a bunch of files (and a lot of other things which might be useful for some people) and has been updated more recently ;)

So when can I expect heightmapped textures of it?

There is a file called "package" inside of the "pk02" folder, just use it, rename it with the same name of the map you want to make. You also can load them with /exec packages/philipk/pk02/package.cfg
Textures will be in the 11 and 12 page of textures.
