Got some major shadow problems with this scene.
One IBL light, at 5% intensity, AO on at strength 1
One specluar only infinite
One infinite light, white, intensity 75%, AO on at strength 1, raytraced shadows, shadow blur 5.0
Global AO settings: RayBias 0.1, max distance 20, samples 7
Units: centimeters.
Ground object: RDNA Macrocosm + the ground planes of LBs CreepyTrees II
Ground shader: color map from Transpond Megalith, anti-gamma corrected, with a noise+cellular for displacement. Displacement is "centered"; about half of the displacement is inwards, half outwards. Global coordinates set to ON.
The same shader is applied to the ground planes of the CreepyTree objects.
I applied material based AO, samples 5, raybias 0.1, distance 20, strergth 50 (!) to the ground shaders.
Render settings: Raytrace 2 bounces, shadows on, irradiance caching 0, minimum displacement bounds 5.0, smooth polygons and displacement maps enabled.
As you can see in the attached image, the light based AO works fine on the figures, as do the shadows.
But for some weird reason I don't get any shadow on the ground, I've tried depth mapped shadows, different blur radius, other ground shaders, nothing helps.
Help!
