2D rendering shadows - Strange result
 
1 Attachment(s)
Hi

I rendered this 3D plan in a 2D view using a directional light and a raytraced shadows in a very high res setting - Shadow rays 5 and ray depth limit also set to 5 and as you can see the shadows on the floor or on other objects have some kind of layered and multiple-transparency effects - the shadows are cast by the wall which is opaque and is a polysurface and also by other objects but I think that the main probelm is by the wall.

HELp as this is urgent.

Hi,

Really I don’t know why the shadow cast by walls is different by the other objects…
Or why don’t you use depth map shadow??? It’s faster to render and you can obtain the same results (see below).
Cheers.

Or if you really want to make ray traced shadows try to increase the shadow value in ray tracing tab from the render options…
Cheers.

I finally resorted to Depth Map Shadows but I had to remove the transparent windows as it casts dark shadows.


regarding your second post - I already have all the 3 parameters set to 10 but it seems this is not the problem.

is this an orthographic view? because if it is it could wreak havoc with the shadow maps. It shouldn't but you never know ;)
