Hellow my fellow archicad octane renderers

unfortunately im quite a newb with the render meta, so i might ask a stupid question:

my problem is that on my rendered picture a shadow occurs beneth the stairs where no shadow should be. and i have no idea wy this is.
i attached 2 pictures. one from the archicad internal engine and one from the rendering.

obove this scene are 2 light surces, 2 morphs with black body emmision.
the lighting in the rest of the scene seems to work.
waht you cant see on this picture is that the shadow of the side of the stairs also has a shadow... a shadow of a shadow might not be right :D

has anyone a good tipp or idee waht im doing wrong?

Hi, I suspect your Kernel->Ray Epsilon is not right. Try adjusting either way to see if the shadows correct themselves. http://render.otoy.com/manuals/ArchiCAD/?page_id=294
