There is a weird behavior when combining actors with RBC. You will only get one mesh at the end, which is not even an actor.
I tried about 1000 actors, it did exactly that.
Maybe RBC is not suited for actors? Then does anyone know any good way to optimize actors?
I am making a RTS game, and the number of units is very limited by the number of actors…
Unfortunately RBC doesn’t work with animated models. I suppose this should be mentioned on the RBC page in the manual. There have been previous discussions on this, for example here. GPU hardware instancing (which is not the same as instancing in the manual) may be your only option.
