Lines in Software Renderer
From VFXPedia
The software renderer can not render lines (as of version 5.1). This includes line style particles and wireframe meshes. Due to the perils of the clock, line rendering was not finished for 5.0 launch. We have decided it most economical in terms of saving developer time to reschedule this feature for the next revision of Fusion where this and related areas of the code will be changing.
