I'm really struggling in visualizing line particles using cycles render...
I'm trying to visualize shortwave solar radiation in a city by using the LINE option (see figure) in the particle properties. I've also tried the OBJECT option, but when using this option the particles do not change direction when they collide with the mesh.
However when using the LINE option, the particles will not render in cycles.. Does anyone know a workaround to this problem?
