Blender to PrusaSlicer: Support canals not being cut out
So I've run into a problem. I'm trying to model a sword, as I've done in the past. As the title suggests, I work in Blender. Before exporting my STL files, I add a groove to put support rods through. Before the most recent Slicer update, this was fine. Grooves would be there when I imported the file to the Slicer. Since I updated, any object I've imported with a support rod groove is completely filled in. I've tried this with a couple different weapons, and its all the same result. I know there's a function to add a modifier to the models in the slicer to create a groove, but when I tried that, it added material inside the groove that I did not want, causing a blockage and preventing the support rod from going all the way through. The attached picture is the Blender object. There's clearly supposed to be a groove in the model, but in the Slicer, it comes in as completely solid. Is anyone else having this issue?
