==== Mode 10: Another reflection mode ==== | |||
This one needs more research done, but the only thing the game does with this mode is load this post-transform matrix: | |||
<pre>0.5, 0.0, 0.0, 0.5, | |||
0.0, 0.0, 0.5, 0.5, | |||
0.0, 0.0, 0.0, 1.0</pre> | |||
The function of this matrix is to transform normalized texture coords so that they range from 0 to 1, instead of from -1 to 1. This mode seems to work well with mode 0's settings, though, so it's possible that the game is creating a texture matrix somewhere else. This needs some looking into. | |||
