Ive been wondering if you could make it so if i mirror car it still would look like one piece instead of looking like two pieces glued together. crash physcics and reflection needed only.
I think what ur asking is up to the triangle density of the model, if the triangles that are mirrored touch each other when u mirroring the model then its cuz the angle at which they meet reflects light in opposite directions, giving u that line that split from front to back which ur describing hope that makes sense
