Bugs

Hi,there.
I’m using ShadowOnlyMaterial for my job and found a bug (may be).

https://playground.babylonjs.com/#N43T8H#2 (no shadow)

https://playground.babylonjs.com/#N43T8H#3 (shadow ok)

the above two links has the same code , what the different is code order.

HemisphericLight first then the DirectionalLight , the shadow is miss.
DirectionalLight first then the HemisphericLight, the shadow is ok.

I think this is a bug, but may be some rules i havn’t read.

thank you
