point normal

Recommended Posts

Hi

I need to have a curve with point normal that is perpendicular to the point itself. In which when I move the position of the curve, the point normal will not be affected. Is there any way I could achieve, maybe in VOP or SOP?

Cheers

calculate the normals before you move the curve ;)

or you could put down a polyframe and a attribwrangle with this line @N = -cross(@N, v@tangentu);

even easier: in polyframe node just turn off Normal and tick on Bitangent and call it N
