Lock Normals

General TouchDesigner Discussion
1

Is it possible to lock normals? I need to move points(deform geometry) of the model but not to change Normals values.

Or

May be there’s a way to save Normals values via chop or dat, then change points positions and then assign Normal values that were saved before geometry deformation? :question:

What SOP are you using the change the point positions? Normals arn’t changed in most SOPs unless they have and you turn on the ‘Compute Normals’ parameter.

3

just wire your SOP before the deformations into the second input of the point SOP (1st input would be your deforming SOP) and in the normal params use $NX2, $NY2, $NZ2

Thanks alot guys! Second input of the POINT SOP helped! Exactly what i need!

I deformed geometry using TRANSFORM SOP
