When to use the Lit Shading Model: You should use the Lit Shading Model if your Emissive Material has to be used in combination with other shader inputs like the Base Color input or the

So whenever possible, use the Unlit Shading Mode as it will be cheaper. There is also no visual difference between the two different Shading Models in terms of how the Emissive is rendered. However whenever possible, Emissive Materials should use the Unlit Shading Model as it will result in a shader that is cheaper to render. Giving off a Bloom effect that you might see when looking at a very bright light source.Įmissive Materials are self-illuminating which means that they can be used with both Lit and Unlit Shading Models. In the following How-to guide, we will be covering how you setup your Materials to use the Emissive input as well as how you can use the Emissive input to actually light the world that you are creating.Įmissive Lighting or in UE4, Emissive Materials, give artists a very cheap and effective way to give the illusion that a Material is casting light when it really is not.Įmissive Materials do this by allowing artist to push the values of the Emissive input higher than 1.0 which will push the Material into the HDR range, Inside of Unreal Engine 4(UE4), Self-Illuminated Materials are known as Emissive Materials.

Turning on or off Emissive Influence on the Worldĭuring the course of project development, the need might arise for a Self-Illuminated Material or glowing Material.
