Hi, I recently started exploring the uses of IrrEdit for lightmapping.
Currently I'm looking at animating the movement of the sun and moon in a realistic fashion in my irrlicht powered virtual reality project, and I'm trying to see about casting realistic shadows.
However, I need to know... Are those textures generated by the lightmapping calculations static, and can we create a scene with an animated lightsource to animate cast shadows?

Hi,
the lightmapping is static, yes. If you need dynamic shadows, try the stencil shadows which are available in irrlicht, although you cannot preview them in irrEdit.

After reading about how woefully terrible everyone's frame rates suffer when using stencils, I had another idea which might still be feasible. Would it be possible, do you think, to render a lightmap for each frame of a very long animated mesh? The shadows dont have to respond to anything but the light from the sun and moon, I'm not worrying about other light sources.

Sure, would be possible, but I think you would need a lot of texture data and some mechanism to create and organize this. I think realtime shadows would be simpler here.
