Cloned meshes make useless edge lists.

[mkultra333]

In 1.7.3, it appears that if you clone a loaded mesh, the clone has pMesh->mAutoBuildEdgeLists = true even though the original has pMesh->mAutoBuildEdgeLists = false.

That might mean that edge lists will be created for the mesh automatically even if shadows aren't active or shadow maps are being used. The clone should probably copy the mAutoBuildEdgeLists of the original.

That indeed sounds reasonable.
At least I see no reason for it to work this way, probably just overlooked.
I don't think it would hurt to create a ticket for it.

I assume this solves the issues you were having here: http://www.ogre3d.org/forums/viewtopic.php?f=2&t=69602 ?

Ticket created.

Yeah, it explained why rendering was hanging, the debug build was spending ages building unneeded edge lists. Unfortunately I don't think my workaround (pEnt->setCastShadows(false)) will work for people using Ogre's in built shadow mapping.
