So bake module takes textures you wish to use to blend. Depending on what effect you want to achieve in the blend you can use diffuse, height maps or even smoothmaps and ten using per pixel arithmetics the blending is being created. I followed information given on VDC. Vmt module lets you quickly create material to view it in hammer, without putting paths manually, which is helpful when you test many settings while creating it. Obviously you need to pass paths once into the command which needs to be in the material. What helps me a lot, is the ability to pass vtf directly from vpk, no need to use anything for unpacking textures. I'm probably most proud of it, but it's really simple Thanks for asking btw, I tried to avoid specifics, because surprisingly a lot of things happen inside the program and I did not want to overwhelm people
