I was working in the compositor and was disappointed to find that the Vector Math node doesn’t exist in the compositor and I had to use XYZ and math nodes to get the desired results.
I made a .blend file with math-node implementations of vector math operations. Download for free:
It’d be cool if the Vector Math node from the shader editor were to be ported to the compositor. It makes sense since the compositor has normal and position render passes. A lot of Blender users want it:
Additionally, the shader editor doesn‘t have the YUV and YCbCr settings in its Separate Color and Combine Color nodes (which the compositor has). Would be nice for all the node editors to have the same Combine/Separate Color functionalities.
