Rendering of line goes black?

Beginners
1

Hello,

I’ve got this simple network that draws a trailed line. I’m not sure why but once in a while the rendering of the line goes black, and then comes back to the red color it’s meant to be. It goes back and forth, looks like randomly.

I would be grateful if someone could look at this network and tell me what might be causing this!

Thank you,

You can avoid this by turning off “Compute Normals” on the Limit SOP’s ‘Output’ page. The normals are flipping occasionally as it gets confused which way to point them based on the point positions.

Ah ok. Thank you! In the meantime I ended up using the Line Thick SOP which gave me a bit more flexibility with line quality.
