KIND Water2

Revision as of 18:54, 18 October 2010

Note: New animated water in TRS (kind water2) supercedes previous UTC water (kind water). Therefore kind water is no longer supported by TRS. Where a UTC map refers to an old kind water asset it will automatically be updated to one of the new animated water assets. Essentially the new water system comprises of an animated, bump-mapped, transparent surface. The animation variables are controlled through the water.anim.txt. The tile size and material properties are controlled though the water.config.txt file. The following example is of Calm Water.
