I tore apart the shaderlab_1337 example map to figure out how alphamod worked. I went to render, loaded it, and for some reason the Alpha_0 shader isn't working. It shows up as the grey box with white stripes. Now, I'm assuming that this shader is an important part to making everything work, but I didn't find anything referencing it in the .shader file for the map. Could somebody please give me the shader file for Alpha_0 or explain how I can make it work?
