haven't done any 3d stuff in a few months, just started again, building similar models to ones I've already built. But simple lights don't work. Plus when I select RPS Render, Edit Lamps - I get
Dialog name must contain an underscore: appl_name: ''
(Error occurred in ..\rps\dlg_layout.cpp line: 143)
Could use some urgent help and due to proprietary reasons, can't upload file
