Falloff maps are a type of map that can be found in most 3D & game engines. These maps can alter the color of an object when parts of information technology start to face away from the camera.
The render engine volition calculate the angles of parts of your geometry in relation to the camera position, and volition add the second falloff color to parts that exceed a certain angle.
The sharper the angle abroad from the camera, the stronger your falloff color will come through.
This can be used to add an ambient occlusion blazon, self-shadowing consequence to sections of your model, without having to make an actual AO map.
Alternatively, if you use a lighter shade on your falloff maps information technology can give more of a backlit type of look.
This is an effect that is unremarkably used very subtly to assistance emphasis some of the smaller details in your model.
If used correctly in sure programs, it can even work to shade the rises and falls in a normal or bump map!
Information technology can also be used equally an opacity map which tin can make objects look translucent, as only the edges take hold of the light in a scene.
Or can use falloff maps to make more interesting gradient patterns if yous desire a more surrealist look to your models. The options seem practically endless.
The interface in your fallout map should contain some kind of bend editor that should be a straight line by default. Editing this curve will change the strength of the falloff and how it affects your model.
If you curve the curve upward to a sharper angle, your falloff color will exist more than prominent on edges than if you modify the curve downward to a flatter angle, which will have the opposite effect.
Falloff maps are a simple tool. But is can be hard learning how to conform them to get perfect results that are subtle enough to not stand out, yet also not so weak that they aren't noticeable.
If you want to practice working with falloff maps, I propose spending some time just playing with the settings in your 3D software of selection until you empathise how they interact in the return.
Once you understand how to use them, falloff maps tin can really bring your work to the next level.
