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...
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.
