This is not a request, I just want to see if this can be done (easily). (Although if anyone is willing to do it I would be forever grateful)
In my map you can upgrade buildings. The image below shows 4 stages of the command center (done with simple 5 doodads shoved together in the terrain editor). Is it easy to make one big unit like in the image? It would have 4 different 'animations' (well, they're not animations exactly, more like different stages)
It would be cool if the not-yet upgraded parts could be turned light blueish (and/or see-through if possible) to indicate the upgrade, but if thats hard then can it appear out of nowhere (doesnt need build anim anyway)?
So.. is it hard to make such a unit? It doesn't need any new models, just some existing doodads put together.
