I sometimes like to experiment with models found on sites like Blendswap. Some of these models, -although brilliantly made-, have so many separate meshes, it isn’t funny anymore. And not all authors have grouped them in a proper way.
I could spend my whole afternoon joining them together in one group one by one. But that wouldn’t be a very fun way.
Is there a way to either join multiple meshes together in one group simultaneously? Or joining them in one mesh? That would also be fine.
