Maybe look at the map config, or better still, read the node as it links to the original forum thread where this info was posted.

What are you talking about?
ALL textures require a shader! You can't really have a texture that doesn't use a shader. Have you not ever set up a .cfg file for any maps in sauer before?

He means a special shader. Perhaps this should be incorporated into the default shader?

yes u can have no shader ... it looks like crap tho ... if your set the shader to nothing ... setshader ... then you can ...

then you need a new one :)

Perhaps you should look at the age of the node before you ask that first question. It was posted Two years and thirty seven weeks ago, so obviously no you do not need SVN.

As for working in Linux, yes it will as it is no more than a texture and a fancy config.
