I'm currently using Blender 2.69. I was reading up on particle systems in Blender's wiki user manual and I noticed that according to the documentation that in addition to having other object primitives emitted as particles that lamps could be used as well. I tried this out using a simple point light. When I tested the particle animation in wireframe mode I could see that my emitter was emitting the lamps, but the nothing would show up in a render. Could anyone tell what I was doing wrong or is this a bug?
It is nothing about particle system actually.
As you see, there are some non-mesh type of objects cannot be rendered, such as lamps/bones/cameras/lattices/empties, etc, since they don't have any solid face to render. However, you can still see their effects around the scene as ususal.
Anyway, other options here would be:
Instead of lamp, use mesh object with Emit shading enabled;
Group lamp with mesh object, set mesh material type to Halo, emit the whole group as particle unit.
- Use mesh object as particle unit, use Emission shader for material setting. (recommended)
