| MatCap texture. |
| Whether to use the pupil mask texture to control the reflection area . |
| MatCap reflection strength. |
Controls how much the MatCap reflection is stabilized against camera Roll (rotation around the view axis).
0 applies no stabilization; 1 fully eliminates Roll-induced offset. |
| A normal map specifically for MatCap reflection. This normal map only takes effect during the calculation of MatCap, and will not be applied to other lighting calculations. It is generally used to spherize the eye mesh geometry. |
| Controls the strength of the normal map. |
