UDK Shadow Problem

tweekedgirl

Hey everyone, I've just been going through the foliage tutorial on 3D Motive, and I'm doing fine with it, but I'm having some issues with my foliage not casting any shadows when the light has been built.

As you can see, in the viewport the lighting is fine, and all the shadows are cast, but as soon as I build the lighting it just seems to completely wipe out all shadows.

Lighting built

I'm not sure where the problem lies as the material is set to BLEND_Masked, and is set to two sided. The directional light is set to cast dynamic shadows, and the static mesh properties are also set to cast shadows. Any help would be massively appreciated as lighting issues seem to constantly crop up for me in UDK!

there seem to be some shadows on the ground plane, have you checked if the lightmap uvs are correct and the lightmap has an apropriate size? For Dynamic shadows activate cascaded shadow maps inside you dominant directional light.

No, that's not fixed it unfortunately. I tried generating a new set of UV's and the light map coordinate index is set to 1, and I also tried setting the 'whole scene dynamic shadow radius' under the cascaded shadow maps to 1 but neither have helped

Problem solved!

Inserted the trees into the map as 'Rigid Body' actors rather than just static meshes and this has completed fixed the lighting issue.

Well the shadow radius is a radius so you will only get dynamic shadows 1 unreal unit away from the camera :P you should a least put 512 if not 1024^^
