What is the substitute for this?

Unless I'm doing something wrong there seems to be no value output and the vector output doesn't work as a substitute.

  • Hi realjayjobes; that is an excellent question!

    There is no longer a Value output for the Vector Math > Cross Product, because the cross product of two vectors always results in a vector. The value of a vector is not defined and in the old Blender it was a mathematical crime to even have a value output. You might suspect the value to be the length of the vector, but it was not.

    To get the desired result in modern Blender, you need a Vector Math node set to Distance.
