Hello everyone, I am working on a model and need to add some edges to the mesh. For some reason when I try to add an edge loop or poly split a face, they do not work. After selecting the geometry I wish to modify, I click the SOP, but they immediately deselect the geometry and ask for target geometry. I try to select the desired geometry but nothing responds. I am confused. I like the idea of Houdini and wish to learn, but it doesn't seem as intuitive as Maya in a lot of ways. I appreciate any help.

Hmm, even though I also tend to have problems with the most basic functions, poly split and edge loop so far have never failed me. I suppose you are using a polygonal object? Are you on object or geometry level? Did you see this tutorial:

Do you maybe have an upstream node selected in the network editor? Just to be sure, click on the last node (yellow border highlight) and then try Edge Loop/Polysplit again. Also it's a good idea to have an up-to-date build installed, though I doubt that's the issue here.

I have same issue and I found a solution in my case.
