So the model in question is more a less a plane, with normals on, there are slight extrusions for the bar where the bolts lie, otherwise its a one sided plane:**Mesh showing Material
The issue In engine is where any light hitting the back of the face, Whether its a two sided material or not, causes this issue, here is a shot of it in a Hallway: **Mesh In-Engine Showing Problem **Backshot of Same Mesh
Here is a shot of the other side of the hallway using the same meshes, but not being hit by the back light ( In this case: Directional Light ) : **Otherside of Hallway
The Issue is also noticeable on the Support mesh which is a complete full sided model : **Support Struct Model with similar Issue
Any idea why this is?
- All Models have two unwraps
- Happens whether material is two sided or not
- Happens with ANY LIGHT SOURCE if stronger than the otherside
