I've got a large number of meshes (100-200) that share four materials, and I'd like to combine them to be able to reduce the draw count from 100 to 4. However, when the player clicks on them / presses a key, I need to make some simple changes to them - rotate them 90 degrees, for example, or change the material to one of the other three.
If I use the normal CombineChildren script from Standard Assets, the draw count goes down as expected, but changes to the object's transform or material have no effect, presumably because that transform isn't what's actually being used by the renderer anymore.
Is it possible to solve this by "uncombining" the meshes, changing the one I want, then recombining them somehow? Since it only happens when the player reacts in some way, I'd rather see a spike during that one frame than a consistently higher ms/f the rest of the time, assuming it can recombine the meshes within 50-100ms or so.
