So, I have been tripping over my own feet with this mod and I finally got it working in Beam! This is a simple lip for the Civetta Bolide. To Do: Jbeam - Jbeaming the lip Finishing stage 1 model - Fix this: (yes I know this mod is not the best currently but it will get better eventually) Photos - DO NOT RE-UPLOAD THIS ANYWHERE WITHOUT MY PERMISSION.
Someone help this dude, I'd learn from it too. I am trying to learn the same as you really. Just making an open top I Series but don't know the rest like JBeam and the rest of it
Try applying autosmooth and set it to around 40-60 degrees, it usually fixes this issue for old models like the Bolide. It is an issue because (I think) they were made with some really old modelling software years ago so the newer version of Blender messes them up
