second camera render only specific meshes

Hi, I'm outlining the silhouette of a mesh when mouseovering by using this technique:

I was originally only using 1 camera but I ran into antialiasing issues. The antialiasing was turned off when the postprocess was enabled on mouseover and then on when leaving creating a flicker on nearby meshes. So I am currently using 2 cameras like in that example. However after checking performance I noticed that adding the second camera doubles the draw calls going from (~70 -> ~140)

Is there a way to tell second camera to only render the mouseovered meshes?

Thanks that worked.

For those wondering what I did:

// Main camera has default layerMask (0x0FFFFFFF)
// Outline camera has layermask 0x20000000;

// When adding mesh to outline
mesh.layerMask = 0x2FFFFFFF;

// When clearing the outline renderTarget (disabling outline)
for (let i = 0; i < renderList.length; ++i){
  renderList[i].layerMask = 0x0FFFFFFF;
}
