[WORKAROUND] Strange Shadows
I'm getting some strange shadow on my simple wall.
Any suggestions?

mhhh weird indeed, never seen it, so hard to say without some source input on this =o

do you have the same thing with different objects ? or only the wall ?

Hmm.. I tested in a clean project.

The wall + terrain + one point-light + environment
and could not reproduce the phenomena.

Probable something else in my original scene that causing the problem.
Will test by turning things off one by one.

Well... I could in fact repeat the phenomena in the clean scene by adding a Environemt Sun as shown in this video. If anyone want to test you can download both model and project here StrangeShadows.zip

Hi,

The issue is because of the 90 degrees angle between the wall surface and directional light.
As a quick workaround you can try rotating your light a bit.
I'll remember about this issue to see if I can do something about it on the engine side.

Aha. Okay. No problem when I know how to avoid it. Thanks

Later:
Yes. Confirmed. This can be avoided by rotating the wall around it y-axis.
Preferable more than 15 degrees. In case of a building or even a city block
I would think that this means that the complete block has to be in more than
15 degrees y-angle to the sun
