Curve tangent doesn't work

Question

I'm following a "ASSEMBLE: Introduction to Procedural Modeling with Geometry Nodes in Blender" course about geometry node and at 7:10 in "Instancing Spoke Connectors", the beams rotation doesn't change when i connect it with Curve Tangle. Have anyone know what i did wrong?

    Hi Tram,

    The Curve Tangent doesn't wotk in your file, because you don't have a Curve, but a Mesh Circle:

    Oh! Thank you very much! Geometry Node are too complex for me to manage. When something doesn't function, I can't figure out what's wrong. Is there any tips to handle it easier?

  • Martin Bergwerf replied

    Yeah, troubleshooting GN is not easy.

    It took me also a while to figure this one out (although, when you know it, it's simple, but you just don't know immediately where to look). I worked my way backwards through the Nodes to see what could be the problem.

    It can be a wrong Node, like in this case, but it can also be a wrong connection somewhere, or (and this can be really hard to figure out) a problem with the logic.

    With time you'll get more comfortable with the system.

    Thanks, that was helpful. I'm properly should need more time to digest this!
