What happens during specular reflection?

What happens during specular reflection?

In specular reflection, the incident light is reflected into a single outgoing direction. Light reflects on a surface known as specular surface (similar to that of a mirror) at the angle of incidence. It is further reflected at a similar angle. Specular reflection rarely occurs in nature, but rather in man-made spaces.

What does a specular map do?

Specular maps are used to define the shininess/highlight on a surface. Typically a specular map is a black and white image that maps out the shininess value on an object. The whiter the pixel, the more shiny the object in that specific place on the texture (or on the texel).

How do you calculate specular reflection?

The reflection vector R is calculated with the following formula:

1. R = 2 * (N · L) * N L.
2. V = Camera Position – Vertex Position.
3. Specular Light = (R · V)n
4. Final Color = (Diffuse Light + Ambient Light + Specular Light) * Diffuse Color.
5. Next: Normalmapping.

How do you explain specular reflection?

Specular reflection is a type of surface reflectance often described as a mirror-like reflection of light from the surface. In specular reflection, the incident light is reflected into a single outgoing direction.

Are there any nodes that do not work in Eevee?

These nodes will not work in Cycles. Eevee supports the conversion of BSDF outputs into color inputs to make any kind of custom shading. This is supported using the Shader to RGB node. This node implements the specular workflow found in other render engines.

What are the settings for subsurface scattering in Eevee?

The subsurface scattering settings used to be something you had to turn on. But now Eevee detects if there is a shader in the scene that uses subsurface scattering and turns it on automatically. There are two settings that both balance between speed and performance.

What does ambient occlusion do in Eevee render?

Eevee ambient occlusion settings Ambient occlusion is a feature that creates shadow where different surfaces meet. For instance in corners and crevasses where light would normally be more limited. By the way, I have a full article here, covering everything there is to know about ambient occlusion.

Why do you need screen space reflection in Eevee?

As a general rule, you could say that the more zoomed in a shot is to a subsurface scattering effect the higher samples and jitter threshold is needed. Screen space reflection is one of two features in Eevee that allow us to create reflections.
