Hi, everyone:  
When I use shadow generator to create shadow, I have following problem.

 ![15](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/2X/8/85c5cf00410cc0bc88f20b9b2a139aace56c31d7.png)

What I mark on the picture, I think, there should be some shadow on it.

Hi @Zcating

It looks like the shadow is not using the right depth range to generate the shadow. Can you tweaks `light.shadowMinZ` and `light.shadowMaxZ` values also check `shadowGenerator.bias`

There is a troubleshooting section in [Shadows - Babylon.js Documentation](https://doc.babylonjs.com/babylon101/shadows)

If you still have an issue, can you please provide a playground?
