Hey. I found a bug with the orthographic lighting - if you turn the specularity of a material to 0, shadows from a Sun lamp don’t appear on it.
EDIT: Wait, maybe it’s something with my material settings. It might be because the sun lamp’s set to Only Shadow, and has both Specularity and Diffuse. I probably should just use Diffuse…
EDIT 2: Okay, it seems like there’s a problem with using only Diffuse with either the Sun or Shadow lamp - it doesn’t seem to do Specular and Diffuse shading separately. It’s odd… The problem is mostly visible when just messing around with the Only Shadow option.
EDIT 3: It also would seem that using Variance shadow maps reverts back to Simple shadow maps for some reason. I can see it in the 3D view, but when I actually play the engine, the shadows are blocky, like usual.
