What is a reflection Cubemap?
A Cubemap is a collection of six square textures that represent the reflections on an environment. The six squares form the faces of an imaginary cube that surrounds an object; each face represents the view along the directions of the world axes (up, down, left, right, forward and back).
How do Cubemaps work?
A Cubemap Texture is a texture, where each mipmap level consists of six 2D images which must be square. The texture coordinate used to access a cubemap is a 3D direction vector which represents a direction from the center of the cube to the value to be accessed. Cubemaps can have multiple mipmap levels.

The texture coordinate used to access a cubemap is a 3D direction vector which represents a direction from the center of the cube to the value to be accessed.
What does a cubemap do?
A cubemap is a texture like any other texture, so to create one we generate a texture and bind it to the proper texture target before we do any further texture operations. This time binding it to GL_TEXTURE_CUBE_MAP : This means we have to call glTexImage2D once for each face of the cubemap.
How do you make a cubemap?
Select Assets > Create > Legacy > Cubemap from the menu, and drag six textures into empty slots in the inspector. Textures for the corresponding cubemap face. Width and Height of each Cubemap face in pixels. The textures will be scaled automatically to fit this size.
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.
How are sample rays used in eeevee renders?
If you are used to Cycles, you know that for each sample rays are cast into the scene from the camera to bounce around and gather data to end up at a color value for each pixel. The more samples we use the more data is collected and the more accurate the final color will be. In Eeevee the samples are used in a process called Temporal Anti-Aliasing.
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 are the different settings for Blender Eevee?
Blender Eevee render settings we will look at are: 1 Sampling settings 2 Ambient occlusion settings 3 Bloom settings 4 Depth of field 5 Subsurface scattering 6 Screen space reflection settings 7 Performance settings 8 Shadow settings 9 Indirect light 10 Film settings
