need help editing normal

Is this the result that you want?customNormals.blend (610 KB)

Now I know. You were using the other object that doesn’t have auto smooth enabled, so when you apply the data transfer it doesn’t enable/save properly.

Do what you did in the video but enable auto smooth before applying the modifier and then it works.

helluvamesh that is exactly what i want, thanks
ja12 thanks now i done, the problem was the autosmooth, work like a charm
