AO and Landscape, shadow fading.

Cronnix

Hi all! I am having issues with shadows on my landscape. I'd like to achieve an effect of shadows being darker under the giant rocks, instead of having same shadow gradient everywhere. Could anyone point me in the right direction, please?

Also another issue I am having, is tied to Cascaded shadow maps. They either tear up with artifacts in shadow (as can seen below) or with artifacts in sunlight, no matter how I play around with settings (I am using dominantDirectionalLight and landscape). Any ideas? I think it is tied to me using landscape, since the artifacts only appear on it.

You could try to use negative lights to influence the lighting under the rocks, if this doesn't work out you could also make a shader which uses the vertex color to darken certain areas.

Thanks for reply! You don't happen to know any tutorial on the said negative lights in UDK? I searched around, but could not find any specific.

I have solved the issue with artifacts in dynamic cascading shadows by simply changing the angle of the lightsource.. doh >.<
