Oh ok yes I have light coming in at an angle, so the normal map edge is catching the light correctly I believe. However the entire west wall is shaded?
This is my current setting: SetSunDirection(0, -1, 0.5)
Is this a location for the sun or pointing direction? Setting SetSunActive(0) seems as if the normal map is not used at all so I'm thinking my sun direction.
When I tried moving in X direction SetSunDirection(1, -1, 0.5) I loose that bevel shine on the west wall. Again I have not played around a lot with it but noticed this didn't light up as I expected.
Screenclip with sun moved to 1 in X direction:
edit - I should note in the screen clips that back wall plane is at Z = 12, so light is not shining directly down.
double edit - I should just try these things out before posting, adding -1 in X direction is shining on my west wall. So the sun direction is a pointer I just need to play around with I think.
