8t88 A slashable grate is a cool feature of a JK level that's sure to help with your review scores.
Slashable grates are surprisingly easy to make.
First, select the default sector and switch to surface mode. Select a side wall and cleave a square on it, preferably close to the ground, 0.2 JKUs high. Your level should look something like this. For this surface, shown selected above, we'll use 08tmshd.mat for the material. Next, we need to make it so that the engine draws that surface.
