I am studying about draw calls. I have a building with five materials. In the world, without lights, it’s ten draw calls (I expected 6, model+materials, but it’s 10). I don’t know why they are doubled. Any ideas?
Also, If I turn on a movable directional light, the draw calls become 25. So how are we supposed to calculate draw calls? Why are they always doubled and ever reach a number five times bigger?
I went from 5 (expected) to 10 just by adding the model to the world. I went to five times more just by turning on a light. So what is going on with draw calls? It’s the only matter I read different things on different threads every time.
