Performance/draw calls


Recommended Posts

To reduce draw calls, ideally you should just have one big mesh with several submeshes (one per material),


The minimum draw calls you can have is equal to the number of active materials


I am making an LCD digit object like:

It sounds like from a performance standpoint, it would be a tie between:

  • 8 meshes & 1 material, controlled by each mesh's visibility.
  • 1 mesh with 8 sub-meshes & 8 materials, controlled by manipulating the materials opacity.

Code to do the controlling sounds easier with 8 meshes, and I am much better with Blender in Object mode.  Please advise if I am wrong.
