Depends a bit depending on which object, but most block-type objects are 4 d3d_draw_wall and 2 d3d_draw_floor calls (so the top, bottom and sides can have different textures).
thanks. I'm making a 3D game and drawed walls wih d3d_draw_wall but it caused performance issues. I found a way to draw blocks with vertex buffer, it's a lot faster.
