When converting reference frames of true vectors as opposed to positions, you need to treat them differently (i.e. ignore any translation). There are a few ways to do this e.g.: - Plug sphere.global.kine.ori and .scl into SRT to Matrix, plug that into a 3x3 matrix (to force the data type), and use that to multiply the normals before the dot product. - Convert the normals to 4D vectors with W=0, multiply them by sphere.global.kine as before, and convert back to 3D vectors before taking the dot product. Note that the above works for true vectors in general but normals are even more special. If there's any possiblity that there might be non-uniform scaling involved, then instead of just using sphere.global.kine you need to plug it into a Transpose node and then an Inverse node first. That's not necessary for uniform scaling because in that case the inverse of the transpose is the same as the original matrix. And all the above applies only to vectors and normals, not positions.

RE: Evaluating ice weight map gen per frame
I assume it's fairly straightforward, because raytracers do this all the time. But never having written a raytracer myself... Just thinking out loud here... You could take the normalized crossproduct of a vector from a surface point to the camera with the normal (in that order), and the normalized crossproduct of the normal with a vector from the point to the light (again in that order), and take the dot product of the two results. Values near 1 mean that the 3 vectors are more-or-less coplanar and the camera and light are on opposite sides of the normal, values near 0 mean that they are not coplanar, and values near -1 mean that the camera and light are on the same side of the normal. So that gives you a value you can use to modulate the strength (although you'll need to handle the case when 2 or all 3 of the vectors are colinear as a special case). After that you'd need to compare the difference between the angle between the normal and camera and the angle between the normal and light, and implement a falloff based on that difference. Just some thoughts... gray P.S. For transforming normals you should use the transpose of the inverse not the inverse of the transpose. I wrote it wrong below.

When converting reference frames of true vectors as opposed to positions, you need to treat them differently (i.e. ignore any translation). There are a few ways to do this e.g.: - Plug sphere.global.kine.ori and .scl into SRT to Matrix, plug that into a 3x3 matrix (to force the data type), and use that to multiply the normals before the dot product. - Convert the normals to 4D vectors with W=0, multiply them by sphere.global.kine as before, and convert back to 3D vectors before taking the dot product. Note that the above works for true vectors in general but normals are even more special. If there's any possiblity that there might be non-uniform scaling involved, then instead of just using sphere.global.kine you need to plug it into a Transpose node and then an Inverse node first. That's not necessary for uniform scaling because in that case the inverse of the
