Hi Lucy, Yup, that all makes sense and works fine now.

(repost) Hi Steve, This is an error in the documentation - it should specify that the cross function is only defined for vectors with three components, i.e.: vec3 cross(vec3 a, vec3 b); //Returns the cross product of vector *a* with vector *b*. (This is because mathematically, the cross product is only defined for vectors in three-dimensional space). Sorry for the confusion - we'll update the documentation to make this clear. Please let us know though if you still have problems when dst(), A() and B() are all three-component vectors.

Using the BlickScript node in Nuke 8.0v6, the following works (A & B are input images), dst() = dot(A(), B()); but this doesn't, dst() = cross(A(), B()); and I got the following error message, Error compiling kernel: Error at line:30 no matching function for call to 'cross' The Blink docs have this, scalar dot(vec a, vec b); //Returns the dot product of vector *a* with vector *b*. vec cross(vec a, vec b); //Returns the cross product of vector *a* with vector *b*. So I'm not sure what is wrong with cross() or whether I'm using it incorrectly.
