[21:58:15] &lt;<font color="#800080">wjp</font>&gt; hi Ryan<BR>
[21:58:33] &lt;<font color="#800080">wjp</font>&gt; I seem to be getting the hang of this :-)   http://www.math.leidenuniv.nl/~wpalenst/bg2/opengl_test.png<BR>
[21:59:13] &lt;<font color="#800080">wjp</font>&gt; covered, greyscale, normal, sanctuary, tinted (greenish and transparent)<BR>
[22:00:18] &lt;<font color="#800080">wjp</font>&gt; I couldn't find a way to do greyscale with a single texture unit, so I used multitexturing there<BR>
[22:00:56] &lt;<font color="#800080">wjp</font>&gt; the first unit does INTERPOLATE with pure white to get a colour in the [0.5,1] range, and the second one applies DOT3_RGB to that to get greyscale<BR>
[22:07:32] &lt;<font color="#B0B0B0">Colourless</font>&gt; yeah you'll need to do it with multitexture<BR>
[22:16:39] &lt;<font color="#800080">wjp</font>&gt; pretty interesting stuff, this opengl :-)<BR>
[22:16:52] &lt;<font color="#800080">wjp</font>&gt; I wonder why I've been ignoring it almost entirely up until now :-)<BR>
[22:21:20] &lt;<font color="#800080">wjp</font>&gt; anyway, time to go again. Bye<BR>
[22:51:59] &lt;<font color="#B0B0B0">Colourless</font>&gt; willem... just wait till you start looking at fragment shaders... so much flexibility<BR>
