I was playing with creating objects on a spline (following the Dominoes.blend example file) Something I did crashed blender. I reopened the file and I can no longer connect the purple spline socket to a purple spline socket. ??? I tried closing blender and starting from a new file. I opened the dominoes file and added new nodes (spline from object, get spline length) and was unable to connect the purple sockets. sockets!

What does it mean when a socket is faded (transparent)?

Thanks

  • $\begingroup$ Transparent mean it expects a list of splines, semi transparent means it expect both lists and single elements (The socket is vectroized). $\endgroup$

The Splines from Object outputs a list of splines by default because a curve object can have multiple splines in Blender. You can see that it outputs a list by looking at the socket transparency.

You have two options:

  • Use a Get List Element node to get the first element from the list.
  • Open the advanced settings of the Splines from Object node and switch the Import Type to Single.
