Thank you for your reply !
Ok, this stencil shadows looks nice at our mdl models, but we don't have them, if you doesn't use the shadow flag for your models :-). Maybe it's a work-around to use 0-high model as the shadow on the floor, but you don't have any shadow at your models itself. The result is very very ugly ! For me this problem with the stencil shadows is a great one, because now it's hard to make nice looking maps with buildings out of more then only a ground floor. To clip the models away when the player comes into the area of my models is hard to do for each office furniture in my maps.
