Mesh Upgrader to regroup duplicated materials

[Jules Robichaud Gagnon]

Hi everyone,

It happens when using Attach with 3DS, the final exported mesh does not regroup the meshes with identical materials. Often, we would need different materials but in some case not.

By example we created a tree with 3 different materials, 1 for the trunk and 2 for the branches. When exported, the tree has 40 different sub meshes, 1 for the trunk and 39 for the billboards. It is not very optimal when rendering.

Would be useful option in OgreMeshUpgrader, isn't?
