When to use emissive material instead of texture?
If the Emissive Material is just to simulate light , then using a numeric value instead of a texture is the way to go. However if you want to simulate lights on an object, using a texture as a Emissive Mask is the way to go as you can define in the Mask Texture exactly which parts should be illuminated.
How to change strength of emission at principled BSDF?
You can manually input values higher than 1 in the red,green,blue fields of the emission color of the principled shader. Keep in mind that this is a workaround and will not mimic exactly how a classic emission shader works when you tweak its strength.
Why do you use emissive lighting in UE4?
Emissive 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.
Why do I not have Tech panel textures?
If you cannot find the Tech_Panel textures that are used in this How-to, that means that you might have forgotten to include the Starter Content with your project. To find this content, you can create another project, make sure to include the Start Content, and then use the Migrate Tool to move the textures from that project into your project.
What are the drawbacks of emissive materials?
The generic white light that is emitted will still be slightly tinted to the color of the texture. If you would like the effect to be more intense, you can adjust the color of the light emitted, as I have done below. Emissive materials do have certain drawbacks.
How to apply a color to an emissive material?
To apply a color to your emissive material, simply select a color from the drop down menu in the Enscape Materials Editor. TIP: To exactly match your material’s color to the color that is emitted as light, simply copy the color value out of the Advanced tab of the albedo color drop down menu into the same space in the emissive color menu.
How are emissive materials used in a scene?
When an emissive material is used in a scene, it is rendered as a visible light source, and depending on the intensity you set, its glow can actually light up the surrounding area. The great advantage of emissive materials is that you can use them to create complex forms that glow; you can get really creative!
