Weird Object Lighting problem

Hello guys! I have a weird problem with my corridor I created for testing, it’s a simple corridor made with a single plane in Blender, collision works great and all, but the lighting isn’t as I expected… Is seems like it recognizes only one side of the mesh and not the other, creating some weird artifacts with the lighting… I tried to duplicate the whole object and flipped the Normals in Blender… Fixed it, but it also made some weird artifacts with the lighting, and I don’t want to create additional polygons as it may reduce the performance and it’s a pain in the *** for me to do the UV Mapping…

Hope anyone can help me with that… I just want to make a simple corridor…

Works! Thank you very much!

There is a tickbox on each mesh instance called something like Shadow Two Sided. It should help.
