What's going on with my draw calls?
So I did some research on draw calls today, starting with a blank level and adding:
What I found (using stat scenerendering) was interesting; For some reason each mesh adds two draw calls to the scene, despite the fact they each have only one material each. So 2 meshes = 4 draw calls. This is not as expected, especially with static lighting. It looks like Unreal is currently doubling the amount of draw calls for each Static mesh for no reason (that i know of). The same thing happens with Foliage instances; paint one mesh with one material x50 and you get 2 draw calls - not bad but certainly not as expected.
Anyone have any insight into this?!
It is probably just the meshes being drawn in the pre-pass in addition to the main rendering pass.
