Scene Optimizer Mesh Combine Issue

[Piyush Bansal]

Hello, I am having a problem with Scene Optimizer I am using default settings After optimizing scene, I see some meshes are solo (small meshes) aren't combined or some are combined with only 2-3 other meshes And they are all very near to each other, So I think if they all have combined together then it would be better results. Is it a bug? Or should i change something in the settings??

Please see these screenshots for reference of what exactly i meant

Please let me know how to fix these kind of things so that scene optimizer gives me the best results

Meshes need to be using the same material to be combined. 
I would combine objects that are the same and in close proximity. 
There is a few things: 
Check the objects (you could break them down more). 
Make multiple Root Game Objects from size and location helps. 
Group objects closer together.
