I’m trying to make a glass outter part here. I negated a cylinder through another cylinder. So I don’t have to make separate glass parts surrounding this structure. But I’m getting these triangle terrors issue.
Roblox glass is just weird, especially with Boolean or meshes. I would recommend just using smooth plastic and making it transparent or anything but the glass material.
Hello, you can try to make the cylinder fully visible first and after that, you can union it again and make it the glass material and give it the transparency(I found this solution on DevForum earlier lol). If it won’t work you can try to export it to a mesh and import it. Usually, it’s solved than in my experience.
You can export the UnionOperation to Blender and remove the inside faces. Also I tried doing this myself and didn’t get this error, do you have the Beta Feature CSG v3 enabled?
