@V0idWa1k3r Hi. I know it's been a good few years since this thread was active but I can't seem to get this code to work. In the renderBox function I found, it takes 3 extra int arguments. I looked at the code and those seem to be color arguments(r, g, b). However, the color only shows up when I'm looking in the positive x, positive z direction. Otherwise, the outline is just black. Do you have any idea why this is happening?
