Question by globalenemy · Apr 23, 2016 at 07:49 AM · lightmappingmodeling

lightmapping problems in blend-model

Hey,

I've created this model in Blender. It's just a room corner. 2 walls and a floor. The walls are semi solid (front face, top face, back face, 0.04 thickness) and the floor is just a plane. I'm making the walls semi solid, because I want them to drop shadows on the floor face. I'm using 3 materials. Floor, Wall and a Clip Material for the outside. (I clip those faces away with a shader, to have no faces outside, but still get the shadow inside. This shader doesn't have any effect on that lightmapping bug)

Now I'm getting my Shaddow. But it's broken.

the second screenshot is from blender and shows a deformed version of the mesh, just to show that my edges are connected and that there are no holes.

Any Idea how to fix this?
