solved Shadow degrade after box moving

[Dad72]

Hello,

I found a problem with moving shadows.

If I create a box with shadows, it is perfect, but if the object, a moment later, is in motion, the shadow of the first box will shake and degrade sharply.

Observe the shadow for 10 to 20 seconds and see how it gets worse after the second box is started moving.

This is because the shadow map needs to resize to be big enough to see both objects. So precision is getting worse.

 

You can force the shadow to not auto extends (http://doc.babylonjs.com/babylon101/shadows#directional-lights)

ok. I see. Definitely, the shadows are really difficult to render correctly depending on the scenes. There are so many different settings that it becomes a lottery game to have proper shadows.

Maybe the cascading shadows will settle everything later?

Thanks

cascading shadow maps are done for this use case: a large scene with different shadows

Is this planned for the 4.0 cascading shadows?

I am not sure I ll have time to put it in but if somebody else is willing to give it a shot ?
