hi again, after installing GI Joe, i've made some experiences that i want to share with you guys!
In tha first image, i've used the the fault sky and ground lights plus the default baker shadows! I think that image is cool, simple but cool ! In the second one, i've modifyed the cylinder and the inner shadow is wrong , after this i've tryed to add a spotlight to fake sun light and add some extra shadows, but there are no shadows coming from that spotlight! How can i solve it?

THX in advance !!
