Irrlicht Engine

Ok: myabe this isn't the right place for speaking about it, but I don't know where can i go so...

I've a problem loading a mesh form .x file.
I've .max and I've tried to export ( using the manual of directX 8.1): in 3ds I see the scene exported while in Irrlicht only few surfaces...

Where is the mistake??

Waiting for answers... thank at all!

That's allright.

Without textures .X files is displyed white.

Another problem is the alignment: maybe you 'll have the scene rotated on I haven't solved this problem but you can rotate the geometry with setRotation.
I've posted an autoreplay for those who 'll have my same problem.
