Why I can't get the shadows when my mesh close to the ground?

[Dog-Cat]

I found that when my mesh close to the ground , the shadow will disappear .

following is my setting :

 

the ball position:

ball.position = new BABYLON.Vector3(0,0.5,0);

 

the ground position:

ground.position.y=0;

 

and then i got the result as the files qp1.jpg

 

when i set the ground position to position.y=-2;

 

I see the shadow ( qp2.jpg ) .  And Why I can't see it when my ground is close to my mesh?Is that a bug?

 

I'm new to this. Hopes for help.

Hi and welcome,

 

It would be great to see this setup in the playground (http://www.babylonjs-playground.com/) so we can debug the scene. Try recreating your scene there (even without textures).

I believe it has something to do with the light's direction/position (which is the problem is most shadow-related questions), but it is very hard to tell without knowing how you configured the scene.

Try changing the bias value of your shadow generator.

Thank you for your suggestion ! I replaced my babylon.js with the latest version , and I found my problem have solved! maybe there is something wrong with my old js document...

I solved that it's because my babylon.js is too old ..  thank you for your answer.

This is one of the key feature of v2.1: automatic projection for shadows
