Spotmask Curvature: case study


Spotmask 1.10 comes with a highly superior curvature render pass.

Our plugin will render the curvature of your image by giving you incredibly precise convex and concave pixel information in both directions: the red channel saves convex, the green channel saves concave geometry deviations. You can easily seperate these two channels and mask the final image for many different effects in post-processing.

Additionally, you can get the “sample radius” to determine surface curvature, and you can chose your own colors for both channels (see menu screenshot).

Spotmask Curvature Output

Spotmask Curvature: saving curvature pass using different sample settings

Spotmask Curvature: separating the red channel (convex) gives you a very precise mask for compositing in Photoshop / Fusion / Nuke Software.

Spotmask Curvature: separating the green channel (concave) gives you a useful mask for compositing in Photoshop / Fusion / Nuke Software.
