I really do not know what is causing this. In pic you can see all ok, until right side of pic on wall. Sorta shiny, reflective.

Do you get the same results without having the texture applied? If so then the object may have a problem with the corner area where you get the shine. It looks like the light is seeping through at that location.

I actually like the lit up side better than the left one. It gives it more 3D depth in my opinion.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
