I am trying to showcase how well OpenGL rendering works for complex scenes and with advanced shading while still rendering extremely fast. I wanted to display the power of being able to use GLSL viewport to get a real-time and accurate display of what the final render will look like with cast shadows and normals. I have run into a problem however with the point light because it does not cast a shadow which I need for every light in my interior house scene. Currently I am using several spot lamps pointed in various directions to give the same effect which works but is not nearly as convenient as using a single lamp. Does anyone have an idea on how to do this?

    $\begingroup$ This is not supported in Blender at the moment as far as I know. Upcoming Blender 2.8 viewport rewrite might eventually support this. $\endgroup$ – Duarte Farrajota Ramos Jun 5 '17 at 21:43

    $\begingroup$ Duarte is right, though using spot lamps can produce quite nice results. Switching to blender game gives you the extra option to soften the shadows, which makes the glsl render look more realistic.
