I'm modeling a simple environment and trying to get some sense of what it looks like with textures early on. Whenever I switch the viewport to either texture or material mode, though, only the meshes that are lit by lights are visible. This is slowing down my workflow because I have to keep stopping to add more lights to the scene to see what's happening. All the lights are also cluttering things up and have to be repositioned every time I move meshes around.
(I've also found the Multitexture/Shadless option in the 'n' menu, but that turns off all lighting information.)
Maya has a nice feature where you can switch from viewing the scene with the placed lights to having the scene lit from a single point light positioned behind the viewport camera. This lets you get a good sense of what things look like with textures and shading without having to place lights through your entire scene. Does Blender have a similar feature?
