Help with Geometry Nodes based Neon Sign (prime)?

tubes experiment.blend (145.0 KB)

Shade smooth looks like trash.

Fillet Curve seems to make a lot of overlapping geometry.

How can this be fixed?

Try the blend file Moder has provided in this bug that I filed.

Thanks.


lol, I have no idea what this is doing. Moments like this make me lose enthusiasm to evangelize people to use Geometry Nodes.

Points with 0 angle between connected points can’t make correct fillet.’

I don’t understand “points with 0 angle between connected points”.

Any idea which values I’m supposed to tweak for my specific situation?

I think I’m just going to give up and manually fix all the problems.

This without using the fillet curve node. Mostly just the M needs fixing.

How about this?

result:

i just muted some nodes and added a subdiv modifier:

That’s basically what I did. Disabled fillet node, added vertex bevel and subdiv to have tighter corners. The M is too tight in my last version and will need manual fixes if I ever get around to playing with this scene again.
