SWITCH CYCLES /EEVEE: This is a toggle button, it allows you to quickly switch between Cycles and Eevee. It seemed very convenient during various tests in the programming phase, so we decided to add it.
ADD SHADOW CATCHER: To add the shadow catcher, make sure you have added a “Plane” in Blender, and that it is selected
SHADOW CATCHER TYPES: This menu allows you to choose the type of Shadow catcher
SYMPLE + REFLECTION: It allows you to create shadow + reflection
REFLECTION + NORMAL: It allows you to create shadow + reflection + Normal map, useful for simulating surface bumps
WATER EFFECT: This allows you to simulate animated water, if the background is, for example, a sea, you could simulate waves, and reflections and shadows (Fully automatic)
Once added the “Shadow Catcher” the Menu will
open with new controllers
REMOVE SHADOW CATCHER: This will remove the material and any other object of the Shadow Catcher simulation, therefore, also the light probe which is used automatically for the simulation of the reflections in Eevee.
SHADOW COLOR: Change the color of the shadow (Black is the best, we kept the choice to test what users think)
ADJUST RANGE: Very important! This value (especially for the simulation in Eevee render) is a value that allows you to adjust the shadow, since it does not exist natively in Blender, a system has been added as easy as possible, so if you don’t see any shadow, or the plane it is black, make sure you have Synchronized the sun (In the previous pages it was explained how) and that you are in render mode. By adjusting this value, you will find the right compromise to obtain a shadow of an object.
REFLECTION slider: This allows you to adjust the reflection value, 0 = no reflection
ROUGHNESS: This value only works if you have set the reflection to more than 0, so it allows you to adjust the surface roughness
REFLECTION PROBE SIZE: This is the control of the size of the reflection simulation plane, it is useful in Eevee render, to set the size of the Probe box (Not available in Cycles as it is not necessary
You can see probe box in this image
ADD DISPLACE: If you press this button you can simulate something like a soil, sand or the like.
The plane will automatically divide into 4096 polygons, that can be later decreased or increase
REFLECTION FADE: This value allows you to soften the gap between the shadow catcher, and the background, it is useful for blending the water and the reflections on the edge of the plane to which you have applied the shadow catcher
Square, Circle: It allows you to choose what type of gradient to create on
your “Shadow catcher” surface whether circular or square.
