Great stuff. Here’s my last bit now. Another example of doing it with static meshes in an array. The main thing I’m trying to say is all your complication is coming from converting formats. IE converting from reading a 12 in the file to a mesh called MeshOneL and MeshTwoR, or something like that.
You can avoid ALL this bunkum by arranging your meshes or data or whatever so that the zero IS in the zero slot of the array etc.
