Block Name
Constructors
constructor
Create a new RefractionBlock
Parameters
name: string
defines the block name
Returns RefractionBlock
Properties
commentsSearch playground for comments
Gets or sets the comments associated with this block
inputs
Gets or sets a boolean indicating that only one input can be connected at a time
invert
Controls if refraction needs to be inverted on Y. This could be useful for procedural texture.
link
This parameters will make the material used its opacity to control how much it is refracting against not. Materials half opaque for instance using refraction could benefit from this control.
textureSearch playground for texture
Gets or sets the texture associated with the node
unique
Gets or sets the unique id of the node
use
Controls if refraction needs to be inverted on Y. This could be useful for procedural texture.
visible
Gets or sets a boolean indicating that this input can be edited in the Inspector (false by default)
visible
Gets or sets a boolean indicating that this input can be edited from a collapsed frame
