THREE.JS does not cast shadows

Question

I was doing a Three js tutorial and this code should cast shadows, but when render shadows does not exists over the plane.

What is wrong on code? I\'m reading documentat

Answer 1

three.js r.74 and r.75 have a bug in which shadows are not always rendered in the first call to render(). This bug has been fixed in three.js r.76dev.

Your work-around is to call renderer.render( scene, camera ) a 2nd time, or to have an animation loop.
