Is there a way to render directly with low level Effect and Geometry or Vertex Buffer?

I ask this because I have a static scene with lots of Mesh and Material Objects so that the JS objects themselves take too much memory. If I can use directly Effect and Vertex Buffer like with raw OpenGL, it can be really helpful. Is there a way to do that or is there a guide so that I can write custom code or extend babylonjs to achieve the goal?

Thanks a lot!

you surely can do that :slight_smile:
