hi,
I've noticed that then entities shadows are calculated depending on the sun
direction , regardless of the entity position ,
I mean the entities are still casting shadows event if they are inside a house (sub level house),
If that’s right then I have to manually switch off the entity shadow (my.shadow = off) every time the entity goes inside the house , then turn it back on when he go out again ?

thanks

correct.

Stencil shadows can also be influenced by dynamic lights if you set the cast flag for the light appropriately. If the interior contains dynamic lights, they could influence it instead.

then if I had a terrain that got some dungeons down in it ,
the dungeons has static and dynamic lights , the only way to do shadows right - I mean when he is on the terrain , its shadow is drown depending on the sun pos, and when he get down to the dungeons, its shadow is drown depending on the static and dynamic lights -
is by using shaders, right ?

You don't have to use shaders for the shadows unless you want advanced, modern effects like those offered by the Sphere plugin. Standard dynamic lights can change the orientation of the dynamic shadow if the light's cast flag is set to on. As long as the player is standing inside the dynamic light's lightrange, the shadow will react to the position of the light.

when i add fog, the Stencil shadows didn't affected, the shadow is still visible, how can i fix this ?

I am trying light and shadow now, but I have some problems, I read the manual and can't find any tutorial to follow.

I tried the following steps:

1. sun_light = off
2. enable shadow_stencil = on
3. add my.shadow = on in action and assigned the action to entity.
4. add another model as dynamic light and assign an action with only 1 line "my.lightrange = 500;"

Now I can see the dynamic light work but the shadow of the entity seems react to sun light.

What is my problem?

you forgot my.cast=on;

Oh yes, after add my.cast=on in dynamic light action the entity cast shadow within the dynamic light range.

But why the entity still cast shadow when not in dynamic light range, is that the nature of sun light, if no other dynamic light the sun light will active, or the "sun_light = off" not work.
