MerkVilson Shows How You Can Create a Camera Distortion Shader for Redshift and Cinema 4D.
Redshift offers multiple camera lens types that include Fisheye, Spherical, Cylindrical, and Lens Distortions. It’s lens distortions that Merk Vilson uses to create a custom camera distortion shader in Cinema 4D. In C4D, adding the Redshift Camera Tag to the camera object allows you to add lens effects. Enabling distortion lets you affect that channel with an image map.
Vilson instead assigns an Xpresso tag where the Redshift Camera tag gets added. Adding the camera image parameters to the Xpresso window, Vilson shows how to connect all the proper attributes to create a custom camera distortion shader. Editing some of the characteristics of the shader can yield some pretty incredible results in a render. Nice!
