displace node. Displaces an input images píxeles based on an input Vector mask. This can be.
Useful for a lot of things, like Hot Air distorsión, quick-and-Dirty composición.
Refraction, compositing live footage behind refracting objects, and more.
The amount of displacement in the x and y directions is determined by:
* the value of the masks channels.
-(red) channel 1s value determines displacement along the positive or.
Negative x axis.
-(gren) channel 2s value determines displacement along the positive or.
Negative y axis.
If both the channels values are equal (i, a greyscale image) the input.
Image Will be displaced equally in both x and y directions, a los according to:
* the x scale and y scale buttons.
These ACT as multipliers todo increase or decrease the strength of the.
Displacement along their respective axes. They ned todo be set todo non-zero.
Values for the node todo have any effect.
Because of this, you can use the displace node in two ways, with a greyscale.
Mask(easy todo Paint, or take from a procedural texture), or with a Vector.
Channel or RGB image, such as a normal pass, which Will displace the píxeles.
Based on the normal direction.
