Here is a shot from a terraineditor I am working on

I cut the calulation time for the shadow-map to about 3 seconds.
(depends of course also on the PC, but the calculation should be done under 7 secs on older
computers)
Still having quite smooth shadows.

The level is fully made in the editor, wich took me about 1 minute...
(its still missing ambient objects, like trees)

Nice, the next step is realtime shadow mapping

Realtime shadows are possible (for RTS)
by simply manipulating the shadowskin according to the model.

Samll units must only draw a few pixels (the shadowmap does not have
a really hight resolution)
By keeping the updates small, its shure possible to make a dynamic shadow
for the moving units.

looking very fine
looks promising

Here with some Ambinet models

Looks pretty neat
Can you specify the way you enhanced the shadows, just being curious

Thanks in progres

its just baking the shadow (with a c_trace determining if a "pixel" can see the sun, then it is dark, else bright)

then a smoothingroutine runs over it, just the same way as you smooth pictures in a 2d Program

here the editor and ingame-scene as video

currently the areas behind the hills where the shadows start look strange. i think it would look much better if you used a lighting equation for baking.

just something simple like:

if(in_shadow) brightness = 0;
else brightness = max(0, vec_dot(normal, light_direction));

you could also modulate the brightness with the light color. falloff isn't needed with directional lighting.

Actually the shadow is not calculated by taking the "suns" position for now.
It takes a fixed position by script.
The sun is actually lightnig from a different direction.

When i align sun and shadow, then the mix of dynamic lightning of the terrain and the "baked" shadow will
look better.

I had a shadowbaker before that was more "realistic" by lighning the terrain in contrast to
calculating areas with shadow. but the calculation took almost a minute then.
