<\/a><\/p>\nFirst, we need some things:<\/p>\n
Make a square texture with colored lines on each third (for a 512 map that’s at 170px and 340px), it’ll look like this:<\/p>\n
You can also add title and action safes to this texture in the proper proportions, 7.5% of width from each side should do it.<\/p>\n Import that texture into a new package in Unreal (because you’ll want to keep using this after your current project is done, right?)<\/p>\n Next, copy in a post process chain of your choosing from UDK, or make a new one of your own.<\/p>\n Label it as a “clean” post process, or whatever you wish.<\/p>\n Right click that one and make a copy of it, calling that one “ruleOfThirds_PP”<\/p>\n Before we go fiddling with the post process chains, we need a material! Quite simply, make this with your thirds line texture:<\/p>\n It is an Unlit, Masked material. Changing the Opacity Mask Clip Value determines at what grayscale value the mask will be on or off.<\/p>\n Plug the RGB output of your map into Emissive.<\/p>\n Make a new Desaturation node, and plug a constant value of 1 into the “Percent” input and your map’s RGB output into the top. This fully desaturates your map.<\/p>\n Make a new “Math -> OneMinus”, and plug the output of Desturation into that.<\/p>\n Plug the output of the OneMinus into OpacityMask<\/p>\n NOW we can go into the PostProcess Chain. Open up your ruleOfThirds_PP.<\/p>\n You see this, it is a copy of your clean post process chain. I used one from my thesis which is fairly simple.<\/p>\n Right click and select “Material Effect”<\/p>\n Drop this into the chain anywhere you like. A PostProcess Chain isn’t like Kismet in that something can have multiple inputs and outputs, so be sure to drag from OUT to IN<\/p>\n With the new material effect selected, insert the material you just made.<\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n
