 With 3 negative values, you will generate a "phantom texture". Phantom textures
 are only drawn into the z-buffer (and not color buffer).

+but not fully documented here for now. 
+A few quick tips:
+ - "BOX" filename prefix (ex: BOX_foo.tga) is used as a clamp-to-edge attribute.
+ - "HDR" prefix is used to set a texture as a "light emitter" (sky, lamp, ...)
+ - "ENV" prefix is used for environment (sphere) mapping.
+ - "ATM" prefix is used for "Alpha-Tested Magnification" vector textures.
+ - ";" operator is used for basic multitexturing in TRI files.
+ - "|" operator for UV coords with multitextured lines in TRI files.

+A few things about the last operator, "#":
 Effective environment mapping (one pass, two texture units) is available using
 a special filename separator for texture field in TRI files : #

 This separator can also be used for shaders, to load multiple textures in the
 hardware (up to RAYDIUM_RENDER_MAX_TEXUNITS on the same line of the tri file).
