Monoceros - Null Input Geometry Error

When I try to construct my modules in Monoceros, it gives me the error: “Some input geometry is null.” But… none of my input geometry is null.

I checked the data structure, I checked that I have no null or empty branches, zip. Does anyone know what might be causing the error?

I’m using curves as inputs and I’m just using a 2D module grid. I was able to get this script to work a year ago, but I lost the file and have to start from scratch.

Thank you!

I was able to get the module generation part to work when I switched to regular Monoceros from Monoceros Pro. But now I’m having issues materializing slots!

Ok, both problems are caused by not ungrouping the module geometry before it is inputted into the create modules component.
