Subject : Keeping a surface normal aligned towards an object
I have a surface whose normal I want to keep pointing towards a specific point (a Null placed in 3D space). So the surface normal needs to be updated each frame to reflect the changes in direction.
Does anybody have a quick pointer as to how to script that? I'm afraid I've never tried accessing/changing object normals in XSI.
