Shadows casting problem

Hello community, I have a problem with shadows in blend4web and I hope you can help me.

I prepared a simple scene with a extremely simple model of a industrial machine to start learnirg blend4web. Now i'm working on the ligthing: I set a lamp with shadows on, cast and receive shadows on the mesh and the plane, but I don't see anything.
I tried to change clip start and end of the lamp, but nothing happens.

I'm doing it wrong, but I don't understand where.

I have attached the blend file, i think it's easier using the file itself.

Thanks in advance to everyone can help me to understand my errors

hi, point didn't make any shadow because light is everywhere.
Just add spotlight or sunlight and everything will be ok

Point can cast a shadow but because all shadow have a direction in Belend4Wen at first you need to change it to sun, then set a direction of the pight and then change it to the point type. It's not so confortble but as is:), in the future we have plan to implement a real behavior of such light source.

It works!
It's not tricky, just not easy to find

Thanks
