Spline Nodes create cables that are intersecting instead of overlapping

[Robert34697021z2yt]

Hi,

I was recently testing spline nodes family in SD (which are super cool btw) and I have noticed that when I use Spline Sample Height with a grayscale node (Anisotropic Noise) to drive the height of cables along the Y axis and make them look "tangled" - Hor. Along Spline (rand. offset Y) - which is probably the most common setup - I get nice tangled  cables but, I can clearly see them intersecting with each other when the brightness of each cable is similar in value (see attached screenshots).

Is there any way to fix that? Some settings I can change / tweak or is it just a side effect of the node itself and how it works?

Best regards,

Robert

Hi Robert,

Thanks for your message.

The blending mode for this node is MAX. It means that it will always pick the higher value. So, when you have similar grey values, the transition between the cables won't be as sharp as what you're expecting (as I understand your situation).

Therefore, you have to make sure that no value is similar from on cable to another. This includes the gradient defining the cables.

Thanks for the explanation. Much appreciated.
