I'm new to cura slicer & installed 4.11 Things ive noticed Materials to not actually install. Nothing on the local drive pertaining to any of the materials i imported (Mainly ProtoPasta) - This is an issue ive seen in multiple 3rd party forums - no solutions found I also cannot find mesh modifiers or any way to add shapes to increase structure strength. - I've seen these in older versions on youtube, but cannot locate them in 4.11, so ill be installing 4.10 Has anyone else had these issues? Found any solutions?
